Interesting you bring it up. I don't know the history of the Cultural Revolution except for the description of it in Cixin Liu's Three Body Problem, but I've been meaning to reference that book in my next comment. There's a description there of the young people, excited about new ideas, delivering psychological and then physical violence to academic professors, because suddenly the technical, physical concepts stopped agreeing with the new social ideas. So the relativity theory must be wrong because everyone is equal and that's not relative.
