EUGENE VOLOKH: “I’ve been struck by the similarity between recent calls for suppressing white supremacist speech and past calls for suppressing Communist speech.” “Communists, neo-Nazis, neo-Confederates — I can’t stand them. They are supporters of ideologies of slavery and murder. They are losers, who lost for very good reason. But their speech should be protected, I think; and the cases for stripping protection from such speech have always been very similar.”

Well, as Ed Driscoll says, “the American Left morphed into the John Birch Society so gradually that I barely noticed.”

We used to make fun of the 1950s advice at my university to professors not to grow beards, as that might make them look like Communists. Compared to the degree of speech/conduct/appearance control at most universities today, that seems quaint.
