But honestly: the stuff about "racial insensitivity" and the words "divisive" and "inappropriate" DO get somewhere in the ballpark of "uncomfortable". I'm trying for a neutral word to capture it. None of this is anything like the historical examples—totalitarianism, religious persecution—that inflate his abstract case. These are still problems today on a scale that dwarfs "cancel culture" and "self-censorship".
He gives historical examples. Instead of giving contemporary examples, though, he hand-waves in a way that absolutely will make one side nod vigorously with their priors. Its BS. Tech executives keep getting treated like moral philosophers because they wink and say "why not phrenology?" in order to pose as victims. Galileo was oppressed by religious conservatives engaging in a moral panic. That's happening now, too.
