is it racist to call a black man a homophobe?

Only if you are a conservative. Dr. Tom (Osborne) is not about to fire him or allow the University to do so, and the people of Nebraska, who are pretty rabid fans, will back him to the hilt. Some in academe @UN might have other opinions, but they'll lose.
