Okay, so here's the difference in my eyes:

Wolfenstein pits you against nazis.
Doom pits you against hellspawn.
Blood pits you against cultists.
Postal is just absurdist.

In all of these former games, I can see the humor.

In Hatred, I really can't.

But I hate censorship more than I dislike Hatred or any other game, so before anyone else gets offended and starts worrying about having their games taken away from them, bear in mind I'd be the last person to argue in favor of that.
