They aren't in your face about the tankie stuff on lemmy.ml but when it comes out holy shit. There was one thread discussing bans for "orientalism" where people were going on about westerners being racist without any hint of irony (that was also where I found out the .ml stands for Marxism–Leninism). I deleted my account there straight away.
At least with lemmygrad.ml you know what you're getting into...
