My favorite example was when there was some comradery in a room about a guy divorcing his wife because she got COVID vaccinated and there was some unfounded ideas about a sexually transmitted thing about the vaccines. It would be interesting if they would allow the audience to have some passive feedback, like thumbs down "I disagree with the stage." Then at least it wouldn't feel like an echo chamber by the loudest while half the audience is just listening curiously in disbelief.
