Thanks to Big tech censorship, there are lots of people who are more anti-establishment right on the fediverse. Lots of fairly large instances. Some of them are real nasty pieces of work filled with folks dropping n bombs and swastikas, some of them are filled with some of the sweetest religious right folks you ever met in your life.

I think one of the biggest differences is that you don’t have the Jerry Springer algorithm trying to match up a bunch of black people with a bunch of KKK members. Most far right instances don’t defederate anyone, but many of the far left instances defederate the moment anyone looks at them funny so despite sharing a platform, typically there just isn’t that much engagement between the two groups. In the middle of there are instances that are more than happy to federate with both as long as they aren’t too big of jerks.
