Both of these professors were/are adjuncts. Tenure doesn't sound so bad, does it now?
Tenure wouldn’t protect you if you spoke any negative truth about AA.
Orly? Please give us 3 examples of tenured faculty who were fired because they spoke "negative truths about AA."
It's just possible that admins would lie about why a firing is happening. Charles Negy, UCF, is an interesting recent case.
If you make a problem for admins, they will indeed look for excuses. You better have a clean slate if you go down the road Negy chose.
