I think the most absurd part of the story is a geology prof getting into it about race relations with a student.
“It’s about the rocks…not the race” is all the professor needed to say. Repeatedly.
Engaging with fools is never a good tactic.
There is a lot of pressure in universities for professors to incorporate propaganda in their courses. Simply sticking to the topic isn’t enough to satisfy the administrators or save the professors from grief.
There is another site that has a post about this called Legal Insurrection. The site is quite good. It’s run by a smart and brave Professor Jacobson at Cornell. This particular thread has few comments but if you click on Home you can see the range of topics they cover.
