Dollars to doughnuts, half the people spouting CRT aren't even serious about it, and they're only doing it to get cred with the universities, but behind closed doors, they still use curse words and racial jokes left and right. Dr. Harris is just one case where the mask utterly slipped, and we saw what a good number of these CRT-types truly think about society.
Still, I suppose it really isn't that unrealisitc that there are people who are eager to earn a good living by spouting off nonsense. It's horribly immoral, but hey, you get to live in a nice house and buy almost anything you want. It's a modern-day Faustian bargain, promote ideologies that escalate racial hatred and social unrest, and you get your chunk of money, not to mention live in a nice home.
