I agree. I am thinking of the campus “safe space” where no one is allowed to disagree with someone. Or, teachers having to provide a “trigger warning” before teaching topics that are possibly controversial, allowing students to exit the room and skip the learning material without academic consequence. Or, altogether removing controversial content like The Color Purple, Huckleberry Finn, or To Kill A Mockingbird - which used to be required reading back in my day precisely because they dealt with important, complex issues. These types of norms (which are wholly new) create and reinforce the notion that you can have a theory and be safe from anyone dissuading you from your theory.
