Maybe the problem is that your definition of fascism is "anyone who disagrees with me"?

Lemmy is turning into a left-wing echo chamber. The mods have declared that right-leaning opinions are not welcome and are defederating from any right-leaning instances. If you declare that half the population is not welcome, you're really limiting your reach. It's also going to be a pain to have two logins, one for lemmy.world and one for the free speech instances.

With lemmy, if someone is squatting a bunch of forums and moderating them, you can always start your own lemmy instance and start your own forum with the same title.
