In one on one conversations, he's right.
In public conversations/debates, it's important to clearly show how wrong the other person's position is, and why, so those listening can be informed. You don't have to be dickish about it, but his non-contradictory methodology doesn't work at all in public conversations meant to convince an audience.

That's what your typical atheist has against them. Even if I actually believe what another person believes, if they're being an elitist snot about it, I'll actually try to whittle away at them. I guess I find absolute belief to be a hallmark of the unintelligent, no matter what that belief is.

Step one: don't compare them to a stubborn jackass.

But sometimes it's so satisfying to basically call someone a moronic asshole.

Hmm I'll this approach on you guys when I try to vegan-ise you next time

Have you tried and tested this?

Absolutely.
I'm atheist. I've had MANY religious friends. They all loved to talk religion with me because I was both respectful and offered different ideas than they heard from their religious friends. Many many times they told me I had given them something serious to think about. At least one eventually quit his church and took a comparative religion course before he moved away.

I've also had many public conversations about religion, many here on the sift. Often (not always) those devolve because the other party takes disagreement as personal insult, and gets insulting themselves. I have noted, though, that in most (not all) of those cases, my comments end up getting more positive votes than the pro-religious ones. I TRY to not be a dick about it, at least until the other party starts being a dick, name calling, etc., but I don't hold any punches when debunking ridiculous lies that religions put forth.

This is important. Especially, I find, on matters of religion. Many christians will say that being a christian is part of their identity. Not simply an opinion they hold, but part of what makes them who they are.

Convincing someone to discard that belief should be done with care and empathy.

How about I respect your beliefs by not assuming that you're only holding onto them until the day I come around to convince you to think like me, by disingenuously pretending to consider your opinions just so I can educate you on mine?

If you assume that people come across their beliefs through mature, thoughtful reflection, then it becomes much easier to call them an ignorant jackass to their faces. Because you weren't going to change their minds anyway.

If you can't respect their ideas, respect their convictions enough to tell them how stupid you think they are.
