. . . and, based whether you are talking about undergraduate or graduate, tenured, tenure track or non-tenured professors - you can also talk about the ever increasing administrative and other duties, unrelated to teaching, that are heaped on the professor's shoulders.

These extra-curricular duties diminish the number of classroom and non-classroom student contact hours available during which to present alternative historiographical views to students.

Subject to how I qualified this post, I tend to think this factor, alone, may have more to do with simply going along with the PC version of the history curriculum than any other reason for the number of contact hours remaining after these mandatory duties are fulfilled only permits dispensing a pablumized version of history.

And, who is it that promulgates such extra-curricular duties?
