How absolute is tenure? Can a tenured Professor express any opinion & still be safe?

I hereby nominate you as my editor. I keep writing phrases that people micro-focus on and it gets me into trouble over and over. I will use your terminology.

Ah, yes, Arthur Butz. The university’s position with him was that he’s allowed to write or think whatever he wants, so long as he doesn’t say anything about the Holocaust in class.

It’s also very different when it’s grad student/professor–the only time I’ve seen that really frowned on was when it was the particular student’s adviser. I’ve known any number of professors married to former grad students in their university.

Agreed.

He’s still at NU. It’s still a somewhat contentious issue, but the University appears to have fairly permanently decided that intellectual freedom is more important than silencing repulsive views.
