lemmygrad is full of full-on tankies, the type who would willingly send birthday greetings to comrade Stalin while imprisoned in a gulag, lemmy.ml once was a default instance and thus has random folks on it but is admin-wise run by tankies and generally seems to serve as the preferred instance for lemmygrad folks to have alts on. Stay away from political communities there e.g. their worldnews community is a silly place. Hexbear is hit and miss, not so much hardened tankies there but wokescolds and random lefties who don’t quite realise who they associate with, why that kind of social dynamics is no good. Might have some inane takes, occasionally prone to dogpiling, but at least you can have a conversation with them.
