It’s just pretty obvious that this guy was angry about Feddit.org not allowing Holocaust denial and other antisemitic posts on their platform.

Yeah… no. According to Feddit’s current rules you can’t call for the overthrow of Israel, compare them with Nazi Germany (check this if you think that comparison doesn’t have weight), encourage non-peaceful resistance against their occupation or even say “from the river to the sea”. This is pretty blatant censorship. I got a warning from the mods before for saying that Israel should be overthrown and replaced with one democratic state encompassing all of Palestine.

shows pretty clearly what kind of comments you can expect there and in which direction the wind blows

Yeah… also no. That’s so that Zionists don’t think they get to say “yeah the war is bad but Israel has a right to defend itself” or some shit without getting the ban hammer. I have never seen the kind of comments you’re talking about in much more radical communities than c/Europe.
