A couple of clarifications, from the links:

1. He wasn't forced to resign. He was requested to resign by the president of MSU.

2. He's still a tenured professor, and he will be returning to that role.

3. The group trying to oust him is the GEU (Graduate Employees Union, affiliated with the AFL-CIO), which represents 1200 graduate assistants at the University.

Apparently Dr. Hsu has made some controversial statements about genetics. The GEU's accusations appear to be about perceived racism.

One of Dr. Hsu's sins was appearing on a program with Stephane Molyneux, a conservative commentator whom they call "a white supremacist". I've watched several of Molyneux's programs and he is hardly a racist. Conservative and white, yes. I guess that's bad enough these days.
