The alt social media are a good place to run away from algorithms and explicit mass manipulation from other big tech, be more free, independent, and spread ideas, but I also think that the fediverse is being filling with people with radical political ideologies, some kicked out of traditional social platforms for this same reason. I’m not saying that we can’t have discussions, but I think that many people are making their own echo Chambers in the fediverse.
I don’t see being radical - thinking differently, behaving differently - as a bad thing per se. We don’t all want to plant bombs at the last night of the proms (sorry, Billy), or even hate people who don’t think/behave the way we do.
