Edit: Denying the holocaust has nothing to do with believing "that history went a different way". Do you even know what you are talking about?
Denying the holocaust is pretty much 100% believing that history went a different way, as in, believing that a historical event didn't happen...
And him saying it in game still isn't that big a reason to permanently ban someone (unless he has already been warned that talking about it would), don't see "retarded historical debate" being against the rules. Finally, before you go off talking about my standards, have I ever told someone denying the holocaust that they're not wrong in a way that isn't sarcastic? And it isn't about banning people from a game, it's about why you ban them, because you disagree with them on something and instead of tolerating their view and telling them that talking about it isn't allowed you just go off and ban them because you're a German who's still living in the shadow of world war 2.
