I think only half of these are true, the other half, not so much. I don't think anyone should necessarily get banned for denying the holocaust, but it's a really stupid thing to deny. Probably not that many people have ever heard anyone deny Holodomor or the Gulags and so I'd be surprised if anyone were usually banned for that. Typically people who deny the holocaust do it for racist reasons. I'd be surprised if that were true for Holodomor or Gulags.

Zionists are routinely defamed on Reddit as is Hasidism. Islam isn't something Redditors like so much either. In fact, Reddit is pretty anti-religion altogether. Christianity definitely gets more hate than the others, but it's not like they're pro-Islam or anything.

No one should be calling for violence or insulting people because of their race. Reddit may be hypocritical in the last few ways, but this dude sounds like he just wants to complain that he can't be a piece of crap and get away with it.
