Jim, I take your question to mean... "Can an Academic Hold a non-PC view of history without fear of losing their position". I think that is what you mean. Anyway, going off of that I would say in some cases yes. But that is just speculation on my part and that should tell you right away my guesses aren't worth two hoots in the holler.
Were I to say no I could tell you that I know of a well respected person, at the highest level of the university system, who wants to join the SCV but is waiting until he retires to do so as he fears for his employment. Logic dictates that he knows more about this than I do. Next time we talk remind me and I'll provide more details but for now that is all I can say in a public forum.
