@evan talks about the "Big Fedi" and "Small Fedi" agendas/factions to describe this, I think.
I"m mostly on the "Big Fedi" side, myself. But I can understand the benefits of the Small Fedi. Google+ was like that, too: you were on with a bunch of computer experts, and if you were a computer person, those are largely "your people", so it's kind of nice.
But it's still a bubble. I try to live in the "real world". Sadly, a big chunk of my "real world", particularly in my geographic area, is it's fully of MAGA people. Who keep saying absolutely batshit things that they think are true, because the regime says so. 🤦
It's hard on the sanity.
