I think there are certain critical professions like teacher or cop where individuals need to be held to a comparatively stringent standard in the views they express, but I largely agree with "a critical culture seeks to correct rather than punish," and don't see why the average schmuck should get fired for something he posted online. One of the best bulwarks against cancellation is strong labor protections, but I can't imagine the likes of the Cato Institute challenging at-will employment any time soon.
