You say that informal censorship is always dictated by class relations ?

That’s an interesting take.

I always saw echo chambers (what you call informal censorship) as inability to cope with a cognitive dissonance. It’s a way to emotionally protect one self from others beliefs.

In more than a way, a semi closed environment like lemmygrad is that, I think.

I don’t see it as censorship but more like a way to have constructive conversations about some subjects.

That’s an interesting take none the less!
