They do, because it's fucking stupid. These ridiculous nancy boys can take their nazi fantasies and stuff them up their poop shoot. WTF. Either they are real nazis, in which case they deserve a solid beating every day for the rest of their lives, or they're just common morons who think this is a valid way of making yourself interesting. Either way, I'm not gonna start crying when that nazi ass is getting kicked.
Creating art is a valid reason to break the normal rules for acceptable conduct and good taste. Morality isn't even an argument. However, this must not be confused for a free pass to be as stupid as you want, and get away with it. Nazi propaganda is not okay. Pretending to be into that stuff isn't cool. Nazis are no better than child molesters, when it comes to how much respect they deserve. Why even try to communicate? Better to just punch them on the nose without any further ado.
