People like to blame progressive ideology for these sort of crazy stuff. But actually, the real culprit is consumerism and customer mentality of students. The professor was suspended because the faculty is terrified from upset customers. Same goes for all cancel culture incidents.

The hyper producticised media , is using the upset sentiment to get attention (racial clickbait triggers) But it's riding the tiger, so it needs to keep pace with its own click bait to not get the customers to hate them and boycott them.

This dynamics spills onto the academic realm. Students at US colleges consider themselves customers. So they must never be made upset. They have silly optic based notions of justice. And the faculty have to comply.

This is what contemporary information capitalism does. Consumes and kill off any sort of idea turning it to plastic product and optics.
