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

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.
I really don't think the specific date of reddit departure is what shaped the politics of either community, especially not when the one you're saying was less shaped by reddit was born out of a political subreddit
Hexbear's site culture is full of in jokes and big on dunking. That's always going to be abrasive to outsiders, even without the whole thing where all of their many emojis were enormous on other instances
