Could you contextualize your view that disbelieved ideas get plenty of play? My knee-jerk is disagreement there. Isn't the vogue of public discourse to immediately halt the the development of unpopular/disbelieved ideas through shaming, ostracization, and gatekeeping?

I see moreso repetition of the accepted ideas (which really are prescriptions with concomitant proscriptions, impliedly or otherwise) increasing as social controls grow stronger. I'm assuming the people that post here are very smart so likely your experiences of discourse are very exceptional. But what about the masses?
