Atheist TV host boots Christian for calling raped kid "evil"

shveddy says...

You are an a-godzilla-ist and that is entirely a practical concession to the fact that you can't really afford giant monster insurance considering recent statistics for giant lizard attacks and indeed going through life avoiding Tokyo at all costs is just kinda a bummer - imagine all the fresh sushi you could miss out on.

You can't actually prove that there never was a Godzilla or that there never will be a Godzilla and you can only assume (not demonstrate) that there is not a Godzilla planet orbiting one of the stars a few galaxies down the way.

All you can really say is that Tokyo is still standing and that all the various accounts of Godzilla's antics across the myriad of B-movies and hollywood blockbusters that feature him as a character seem to have no basis in reality for various reasons. You move on with your day, smile a bit and never really bother to duck for cover.

And that's all we're saying about God. To my knowledge, that is the bleeding edge of audacious claims being made by anyone who is even vaguely respected - simply that we can't take religious claims seriously any more, so we are going to move on with our lives, only dealing with religion directly when it decides to be a bit too influential for our tastes.

But fine, based on the secondary predicate principle and a lengthy philosophy 101 essay with no shortage of verbal meandering through Descartes, et al., atheists kinda sorta make a claim of some sort. What's your point.

And if you think that the atheist experience simply trawls the bottom of Christian intellectualism then who would you have them debate, Ray comfort? Matt Slick? Perhaps you?

More than anything, the most disgusting trait of Christianity is that it equates child rapists and children as equally sinful in the eyes of God. There are certainly various arguments saying that different consequences will be felt here on earth, or perhaps that there is an arbitrary age of innocence, etc... But almost universally, Christians agree that the following scenario is at least possible:

Rapist rapes child, we'll start with that.

The child struggles through the resultant torturous anguish across a lifetime, starts a support group, mans a hotline, works in the community to support fellow victims, increases awareness and so on while loving his/her family and friends, making mistakes periodically and occasionally letting loose at a concert or something. The child (now an adult) is unfortunately just a minimally observant Jew and never really gave Jesus any consideration, so when he/she gets hit by a drunk driver at the unfortunate age of 34, he/she is tormented in hell for the rest of eternity.

The rapist, meanwhile, goes on with his (statistically probable) life, perhaps he rapes some more children (also statistically probable) and maybe he then stops at some point, realizing it is wrong and maybe even feels guilty about it. Ridden by guilt, the preaching of a wayward street preacher catch his ears one day. He ventures into church for the first time. He is moved. He proclaims his belief in Jesus and the resurrection. He feels his sins are forgiven and he can feel years of guilt being washed away. Maybe he even admits his history as a rapist to a sympathetic inner circle of confidants, spiritual advisors and friends. He dies of a heart attack, and spends eternity in heaven.

That is disgusting and a god that sets such a system up is disgusting.

Many compassionate people are blinded into thinking this is just and good in an effort to tenaciously preserve their own sense of eternal safety and cosmic worth at all costs. That is less disgusting just because it is an understandable impulse, but it is disgusting nonetheless.

Everything Wrong With The Avengers In 3 Minutes Or Less

poolcleaner says...

Isn't that the Negative Zone? I'm fairly certain it works like however Marvel wants it to work. Sort of like the Power Cosmic. Stupid review judging it as a movie outside the bounds of comic book conventions.

Comics are silly, convoluted, and prefer form over function:

1. Thor and Iron Man are required to have pissing contests.
2. Sunglasses and eye patches make people without super powers look badass.
3. Banner on a motorcycle is a good juxtaposition against his Hulky-jump-through-the-air travel form.
4. Loki is a conceited god so the Iron Man delay works -- didn't this reviewer. already assess that Loki was there to convert and not kill?
5. Of course CAPTAIN AMERICA just jumped from a plane. Idiot.
6. Did he just judge the movie according the Captain America's silly costume? Idiot.
7. No lap dance? He wants to watch the Russian dude give Black Widow a lap dance? I'm confused.
8. Bad guys running laps happens in... most action films with bad guys that need to fill in some time and guide direction visually. Reeeaaaally dumb criticism.
9. Plasma screens? You'd prefer to see a cell phone and then a split screen with 4 other people on cell phones? WTF
10. Loki's scepter is also a space phone??? My phone is also a camera, GPS, medical adviser, blogging tool, gaming device, and if I could download an app that performed mind control, I would. Loki is a god so he can.
11. The hellicarrier was created by Jack Kirby. Fuck you, this is an Avengers movie.
12. Sweeping cameras may sound silly, but comic book logic dictates that this is fine. Why not?
13. His criticism of little girls being able to find Bruce Banner is a criticism of our emotional attachment to the Gavroche, not the Avengers. Is the mystique of a street smart urchin gone from our collective unconscious?
14. Hawkeye's virus arrow is perfectly executed and makes sense according to his abilities.
15. Thor being easily tricked by Loki using low brow tactics is true even in Norse mythology. What exactly are we critiquing here?
16. Loki's objective in being captured is partly him being an overly confidant asshole god. He's just sort of going around half cocked because he can and likes to do so. The gods aren't smarter than us, just more powerful and with magical abilities that trump technology. In fact, this means they don't need to try as hard and would definitely be candidates in the personality disorder department. Hell, for all we know they could suffer from intellectual disorders that would never have become an issue (aside from making them stupidly violent) considering their power.
17. Hawkeye versus Black Widow is not cool? Damn.
18. Fury also gave an intimidating death stare in Jurassic Park when Nedry's "Ah ah ah, you didn't say the magic word" security screen pops up. HOLD ONTO YOUR BUTTS. I liked the half reference.
19. If you have trouble understanding the powers of Mjölnir, why do you also complain about the plodding exposition?! These things require exposition and it's so arbitrary that it becomes plodding. Comics are FILLED with plodding exposition because of this and there's a point where you just have to know the characters. Do they explain superman's laser eyes in the movies? Actually... do they?
20. Black Widow is a weapons expert, including theoretical weaponry.
21. In the comics Hulk learns to control his powers and can even be intellectual in said form.
22. The alien invasion would do more damage than a nuclear bomb. These villains enslave entire worlds.
23. The ending requires homework??? THE ENTIRE SERIES OF MOVIES REQUIRES HOMEWORK.


That being said, I agree with a good number of the points:

1. The tesseract was a rebranding of the Cosmic Cube which has a long history in the Marvel universe. (So I guess this movie was made for comic book fans?)
2. Well lit facility. There should have been some sort of cloaking shield around it, which is perfectly acceptable in a comic book world, if not the real.
3. Cap's bet. I don't believe Cap would have done that because it isn't just.
4. Speaking in English to Germans. It would have been cool to hear him speak in German. Damn!
5. Hawkeye's arrow fucking up the hellicarrier. However, I could see this happening in a comic book, I just don't like it.
6. Captain America's ear piece and bad aim.
7. Tesseract mind control wearing off after blunt trauma.
8. Cap's super powers are kinda lame in these movies, but I'm sure if they weren't, then this review would contain criticism about how his human fists can smash through metal.
9. The aliens are a pretty shitty replacement for the Skrulls. This is what makes me the saddest.
10. Imiatating transformers... this bugged the crap out of me when I first saw the trailer. UGH!
11. Thor's lightning must have a long cooldown.
12. Yeah, it was pretty lame when the aliens died after they were cut off from the mother ship. Inferior to the Skrulls fo sho.

Bill Nye: Creationism Is Just Wrong!

shinyblurry says...

At present this concept of design is just castle-in-the-sky nonsense. Empty piffle. A complete non-starter.

This is why the "mere mention" of "design" will get you "banned" from peer-review, because you could just as well have made a "mere mention" of Bigfoot and the loch ness monster in your zoology report, it's a big tell to your peers that you are a nut who fails to understand the nature of evidence and science, and a big sign that you are in for some fuzzy logic and dumb assumptions instead of solid science.


Design is a better hypothesis for the information we find in DNA, and the fine tuning we see in the physical laws. The reason design is a non-starter is because the idea this Universe was created by anyone is anathema to the scientific community:

Even if all the data point to an intelligent designer, such an hypothesis is excluded from science because it is not naturalistic."

S. C. Todd,
Correspondence to Nature 410(6752):423, 30 Sept. 1999

It is not that the methods and institutions of science somehow compel us to accept a material explanation of the phenomenal world, but, on the contrary, we are forced by our a priori adherence to material causes to create an apparatus of investigation and set of concepts that produce material explanations, no matter how counterintuitive, no matter how mystifying to the unitiated. Moreover, that materialism is absolute, for we cannot allow a Divine foot in the door.

Richard Lewontin, Harvard
New York Review of Books 1/9/97

No evidence would be sufficient to create a change in mind; that it is not a commitment to evidence, but a commitment to naturalism. ...Because there are no alternatives, we would almost have to accept natural selection as the explanation of life on this planet even if there were no evidence for it.

Steven Pinker MIT
How the mind works p.182

After essentially nullifying and disproving everything we have learned about biology the last 200 years, you still have all the work ahead of you, I'm afraid. You now have to build a completely new framework and model for every single observation ever made in biology that makes sense of it all and explains why things are the way they are. Shouting that a thing is "complex" is not cutting it, I'm afraid. You need a new theory of DNA, Immunology, Bacterial resistance, adaptation, vestigal organs, animal distobution, mutation, selection, variation, genetics, speciation, taxonomy... well, as Dobzhansky put it: "Nothing in biology makes sense except in the light of evolution" That quote is more relevant than ever.

Your error here is conflating micro and macro evolution. Creation scientists believe in micro evolution and speciation. That is part of the creationist model of how the world was repopulated with animals after the flood. Macro evolution, the idea that all life descended from a universal common ancestor, is not proven by immunology, bacterial resistance, adaptation, animal distribution, mutation, seclection, variation, speciation, taxonomy etc. The only way you could prove it is in the fossil record and the evidence isn't there. They've tried to prove it with genetics but it contradicts the fossil record (the way they understand it). So Creationists have no trouble explaining those things..and common genetics points to a common designer.

You dont have to trust scientists, most of the EVIDENCE is RIGHT FUCKING THERE, in front of you, in your pocket, in your hand, around your home, in every school, in every home, in every post office or courtroom, in the streets. ACTUAL REAL EVIDENCE, right there, PROVING, every second, that the universe is billions of years old.

Every scientist since Newton could be a lying sack of shit, all working on the same conspiracy, and it would mean fuck all, because the evidence speaks for itself.

The earth is definately NOT ten thousand years young.


Have you ever heard of the horizon problem? The big bang model suffers from a light travel time problem of its own, but they solve it by postulating cosmic inflation, which is nothing more than a fudge factor to solve the problem. First, it would have to expand at trillions of times the speed of light, violating the law that says nothing can travel faster than the speed of light. There is also no theory compatible with physics that could explain the mechanism for how the Universe would start expanding, and then cease expanding a second later. It's poppycock. See what secular scientists have to say about the current state of the Big Bang Theory:

http://www.cosmologystatement.org/

As far as how light could reach us in a short amount of time, there are many theories. One theory is that the speed of light has not always been constant, and was faster at the beginning of creation. This is backed up by a number of measurements taken since the 1800s showing the speed of light decreasing. You can see the tables here:

I have a concession, perhaps a confession to make. An admission if you will. I accept your thesis:

Bill Hicks - "It's just a ride" in Kinetic typography

shinyblurry says...

Ecclesiastes 1:14 I have seen everything that is done under the sun, and behold, all is vanity and a striving after wind.

This world is temporal; it is passing away. These monuments of human achievement we have constructed to declare our own glory are all sandcastles awaiting high tide. They are grains of sand being washed into the cosmic sea. We will leave this world the same way we entered it; at the complete mercy of forces beyond our control or understanding. This American dream is a shadow play; there is nothing from this world that can completely satisfy us:

Ecclesiastes 3:11

He has made everything beautiful in its time. He has also set eternity in the hearts of men; yet they cannot fathom what God has done from beginning to end.

We know there is much more to this life than the gratification we can squeeze out of this moment. There is a perpetual, lingering dissatisfaction, when your hope is resting on shifting sands. Uncertainty is lurking at the doorstep, trying to sell us a lifetime subscription. A guest pass on a prison ship made of mind and sinew. We hunger for we don't see; a sense of permanence. A place called home. Something to fill the gap between heart and mind. We thirst for an eternal wellspring, welling up into life everlasting. A joy inexpressible and full of glory. We know there is more because He set it in our hearts to seek after Him. We know all of the ways of this world lead to death, but when put away uncertainty and seek after Him with all of our hearts, we will the find the bridge to eternity; we will find our Savior.

John 14:6

Jesus said to him, “I am the way, and the truth, and the life. No one comes to the Father except through me.

The Science of Lucid Dreaming

Why is it Dark at Night (or, Why ISN'T it Dark at Night)?

messenger says...

He doesn't say that CBR is only far away. He says that if you look in the space between the stars, there's still light, even there. That's to say, only the CBR exists in those directions, and only CBR light comes in from that distance away. The wording could have been better for people who don't know this, as it could sound like it's a ring of light that doesn't come to us, as opposed to light that does come to us, but so shifted that we can only see it with microwave telescopes.>> ^GeeSussFreeK:

Covers a lot here, just to clarify (and he most certainly knows this) that the cosmic background radiation is everywhere...not just far away. He probably meant that, but it isn't what he seems to say towards the summery at the end. That is, of course, is if my understanding of the CMBR is correct. Anyone care to clarify further?

Republicans are Pro-Choice!

gorillaman says...

I didn't want to join this tired discussion but decency requires someone oppose the appalling 'birth is magic - never kill a newborn' consensus. This is superstitious nonsense; wads of animal meat aren't supernaturally imbued with humanity by being shoved through a cunthole.

There's confusion and arbitrariness everywhere on this simple topic because nobody bothers to ground their moral sense in any kind of rational foundation. They look at a cute baby and their instincts and emotions destroy any hope of intelligent thought. Forget abortion, stop thinking about babies and heartbeats, it's moronic; go back and work on your basic understanding of ethics.

Why don't we kill people? Is it because we haven't been given a mandate; that there's no explicit cosmic distinction to separate one lump of matter from another, giving one the right to disrupt the other? Then we're all just bits of physics bumping into each other, and there's still no reason to prefer a foetus to its host; no more than a cancer sufferer to their tumour or indeed the whole of humanity to a grain of sand.
Is it because they're alive? Then we'd better learn to photosynthesise, because our existence requires the daily destruction of life. Life has no inherent value. It's just one peculiar way that our universe is shaped by its bizarre physical laws, with no mystery or significance - unapprehending molecules forced into the illusion of purpose.
Is it because they're human? Why do we value that species, is it only that it happens to be our own, or is there some particular quality of humanity beside their kind that requires moral treatment? There must be, or else to be consistent we would say that when a rock shatters another it commits a terrible crime among rocks, because one may not harm ones own kind.
Isn't it that we don't kill people because we recognise that the aggregation of their perception and understanding of reality, their cognitive excellence and continuity of personal identity gives rise to the new phenomenon of Mind - I give Mind a capital letter in that silly and somewhat religious way because it is the absolute centre and cause of moral necessity; without it there is simply no reason to be moral. Only by the application of Mind can there be a reality to be moral in. Mind is the universal source of all meaning.

So the question you ask yourself when considering the rights of a creature is 'what is the condition of its intellect; to what extent is it conscious; is it Mind?'

Everybody already agrees with me if they had the sense to see it. If I could produce a tomato with a mind equivalent to a human, which I was able to demonstrate could think and talk and feel and reason like any one of us, would we be happy to chop it into a salad? What about a human with the mind of a tomato? Well they already exist; they're called babies.

Bill Nye: Creationism Is Not Appropriate For Children

poolcleaner says...

^ Don't forget Sodom and Gamora (rape and genocide), which leads to Lot and his daughters (incest). Also, the story of Job (torture of a good man and the murder of an entire family over a bet between cosmic beings) is pretty fucked in the head. No, no, children definitely read and know these stories.

Spanish Pensioner Destroys Fresco with Botched Restoration

14 BILLION YEARS OF EVOLUTION IN ONE MINUTE

shagen454 says...

Boner: It is still confusing...

Astrophysicists have created the most realistic computer simulation of the universe's evolution to date, tracking activity from the Big Bang to now -- a time span of around 14 billion years -- in high resolution.

Created by a team at the Harvard-Smithsonian Centre for Astrophysics (CfA) in collaboration with researchers at the Heidelberg Institute for Theoretical Studies (HITS), the Arepo software provides detailed imagery of different galaxies in the local universe using a technique known as "moving mesh".

Unlike previous model simulators, such as the Gadget code, Arepo's hydrodynamic model replicates the gaseous formations following the Big Bang by using a virtual, flexible grid that has the capacity to move to match the motions of the gas, stars, dark matter and dark energy that make up space -- it's like a virtual model of the cosmic web, able to bend and flex to support the matter and celestial bodies that make up the universe. Old simulators instead used a more regimented, fixed, cubic grid.

"We took all the advantages of previous codes and removed the disadvantages," explained Volker Springel, the HITS astrophysicist who built the software. Springel, an expert in galaxy formation who helped build the Millennium Simulation to trace the evolution of 10 billion particles, used Harvard's Odyssey supercomputer to run the simulation. Its 1,024 processor cores allowed the team to compress 14 billion years worth of cosmic history in the space of a few months.

The results are spiral galaxies like the Milky Way and Andromeda that actually look like spiral galaxies -- not the blurred blobs depicted by previous simulators -- generated from data input that stretches as far back as the afterglow of the Big Bang, thus portraying a dramatic cosmic evolution (see the above video for a sneak peek of that evolution from four billion years after the Big Bang).

"We find that Arepo leads to significantly higher star formation rates for galaxies in massive haloes and to more extended gaseous disks in galaxies, which also feature a thinner and smoother morphology than their Gadget counterparts," the team states in a paper describing the technology.

Though the feat is impressive -- CfA astrophysicist Debora Sijacki compares the high-resolution simulation's improvement over previous models to that of the 24.5-metre aperture Giant Magellan Telescope's improvement over all telescopes -- the team aim to generate simulations of larger areas of the universe. If this is achieved, the team will have created not only the most realistic, but the biggest universe simulation ever.

this video is a waste without addition information.
what am I looking at. spiraling gas' or something.
what is the significance, why did nine people upvote something they probably do not understand.
what part of the universe is this ? why didnt it start at the beginning ?
WHY WHY FUCKING WHY.
