We're not talking about a random "beat up this picture" game, or at least, that's not the impression I got (if it IS user-generated, then I retract my statements re Spurr). We're talking about a game specifically about beating up Sarkeesian.

First, it's the old comedy motto... "punch up, not down". Sarkeesian has received multiple, unbelievably vile threats against her. More to the point, those threats are credible. She's not a famous celebrity with an army of bodyguards to protect her. There's a very real chance that someone could just assault her on the street, far more so than Bieber.

Second, the people that want to punch Bieber are doing so because he's annoying. There's really very little malice behind it in almost all cases.

You can't reasonably argue that's the same for Sarkeesian. There is a genuine and widely documented movement of people on the web who have expressed serious hatred of her.

Let me put it this way, if I compared a "Punch Bieber" and a "Shoot Bin Laden" in the head game, which would you say has more genuine ill intent behind it?

When someone did shoot Bin Laden, everyone cheered. If someone seriously assaulted Bieber, even people who are annoyed by him would say that's going too far.

OTOH, if someone seriously assaulted Sarkeesian, there is a sizeable group of people who be delighted by that.

We don't make judgements in a vacuum. We must take what we know of the context surrounding something to decide whether we like it or not.

A game about punching Bill Cosby in the face? We can reasonably assume it's motivated by sexual assault allegations.
Now take the same game, and instead of Bill Cosby, you can choose any black celebrity. Again, you can make a reasonable assumption, except this time we could say it's racially motivated.

Possibly I'm misinterpreting his intentions, but if so, he's not really attempting to correct the public perception of them.

You know what I hate: bad, bad, terrible, horrible, not even contrived impressions of people.

This guy is not even trying anymore.

You'd think he'd want to make up for the fact that he's a white guy doing a black celebrity by at least getting the mannerisms and voice on target.
