There are communities around Lemmy dedicated to “just making lists” of leftists who also consider a middle school anarchist using an emote of Stalin as supporting genocide.
As far as I have been able to discern: a lot of reddit transplants got called nazis by established lemmy communities, so there’s kind of this whole weird internal Lemmy movement to try define ‘tankie’ as widely and negatively as ‘nazi’.
I mean, you’d think OP would know what instances they would want to block from, you know, using Lemmy. They seem to know what is ‘cringe’, but want or need that anti-leftist qualifier for good measure.
