It sounds like, so far, the University of Colorado has it right. If he’s canned, it should be for his fraud and plagiarism, not his inspeakably vile utterings (or character).
I have mixed feelings about what the eventual outcome should be. In the interests of academic integrity, the university should get rid of him (and I suspect that it will, and I hope not with a buyout). On the other hand, I think that in a just world, they should have to live with him as punishment for hiring him in the first place, and as a constant reminder to be more careful when granting tenure.
