I’m a little hesitant to wade into these waters - I’ve not been around Lemmy long and know Lemmygrad only by reputation - but I was a r/CTH lurker/commenter before it got quarantined, during the quarantine, and right up until it got banned, and from what I remember, the kinda tankie stuff I’ve heard that Lemmygrad espouses (however jokingly/sincerely) would get the kind of real pushback on CTH that started slapfights and flamewars. Idk how strong the “those bastards killed Rosa” component is over at Lemmygrad or how effectively they counter tankie bs, mostly because I’m too old and busy to bother with things that don’t enrich my life (like arguing online). Consequently, I absolutely understand and sympathize with not wanting to waste whatever precious time someone might have left to live engaging with genocide denial and other authoritarian handwaving.
