The biggest surprise for me was the https://hexbear.net count, an instance I hardly interact with.

              Horseshoe theory is essentially Latte-Flavored horseshit

              The horseshoe theory does not enjoy wide support within academic circles; peer-reviewed research by political scientists on the subject is scarce, and existing studies and comprehensive reviews have often contradicted its central premises, or found only limited support for the theory under certain conditions.[6][8]

      It’s essentially where reddit’s old Chapo Trap House community went after reddit banned them in 2020. It started federating with the rest of the fediverse some time last year, but there was a bit of a culture clash between it and some other larger instances and several of them defederated it

        To be fair, that’s because liberalism is closer to fascism than any sort of leftism, and many of these instances have a strongly liberal user base because many were with Reddit longer than most leftists were.

      It’s an instance mostly based around authoritarian communism. They got banished from Reddit quite a bit before the black out.

      It’s a leftist server. LW defederated from them months ago because they have some, well, interesting takes on things like the war in Ukraine. I can’t recall the exact cited reasons for defederation but I’m sure you could find the defederation post on lemmy world’s announcements page.

        Most instance defederated from because they are tankies that talk a lot of bullshit. However, im not entirely sure if I would really call them leftists. More like communistic Authoritarians, yes, communism is something mound mostly in left communities, but not to sure if their takes on human rights for people with other opinions and stuff like that makes them really left.

          I’d be comfortable calling many of them red fash but I was trying to be diplomatic.

        .world never federated with Hexbear from what I remember. I’m pretty sure they were on the block list before Hexbear got federation completed. There was no single incident as far as I know.
