I wasn't thinking of actual censorship. The bad ideas arise because the people in question are being funded by a government that doesn't really care or have any way to judge whether the ideas are good. Just requiring them to find their own funding would go a long way. It wouldn't stop DiAngelo now because she already gained critical mass and found ways to parlay that into money via training programmes, but would this stuff have arisen without large numbers of bored humanities profs looking for some meaning and purpose, and able to spend so much time on this thanks to grant money?
