So I'm not all that convinced by this argument. I observe in a lot of ways the classical liberal movement has a very narrow perspective on the acceptable range of beliefs; for sure "wokeness" has spread like wildfire, and I have my criticisms, but I don't think the people who care do so because they lament the loss of academic freedom, it's just annoyance at feeling like they lost control of the narrative. PG's recent screed on free speech was reviewed by a whose who of people who have a very narrow set of "acceptable" liberal beliefs.
