I’m done, I’ve been banned for expressing a different opinion (without insulting or personally attacking anyone), I’ve been accused of evading a ban with multiple accounts (this is my only account I’ve ever had on any lemmy instance), I’ve had people selectively ignore my comments and accuse me of things which I never said, and I’ve had people ignore valid criticisms and keep attacking me.
Reddit has many issues with trolls, one-sided discussion, and just general bullshit, but many Lemmy instances are way worse. The newfound freedom of Lemmy has attracted many extremists, from both sides, and many of them are moderators, who are more than happy to remove any contrarian opinions. This results in discussions being echo chambers
It’s not so much that there is a wraparound. Or any sort of “horseshoe”. It’s that authoritarians are authoritarian first. Notions of left or right boil down to what’s convenient to them as an afterthought.
The actual extreme leftists are generally pretty chill and supportive. Unlike authoritarians.
