Games should be able to have whatever the forget the creator wants to put in them. Who cares what the game has, the real question is if what it has makes it good. Hatred didn't suck because of the Flash Mob, it sucked because a controversy built it more hype than its gameplay (lacking), story (absent), artistic message (lol), and every other aspect combined could live up to.
And I'm glad Sarkeesian has spoken out against the violent nature of Doom. Maybe after she's done undermining her own credibility people will start to realize a lot of the other stuff she says is bullstuff too.
