depends, if you are banning me for using slurs I wouldn’t think you’re in an echo chamber, even if I was the biggest bigot on this planet, however, people on lemmy have banned me for stating my opinions like “I don’t want to live in an autocracy” or “kamala is still better than trump”
usually russia, but china as well
also just for clarity: I’m an anarchist, I don’t like any state, so pointing out that the US isn’t better doesn’t help the discussion (sorry if you had to read this, I still got traumatized by the stupidity on grad)
