Well, I’d need to meet these guys or know more about them to be sure, but they all sound like decent people who went into this line of work and studied hard because it’s what they wanted to do in life.
Nothing wrong with medieval history. Everyone should have basic history and literature courses—ancient history, medieval, Renaissance, etc., as well as whatever their specialty is. One of our problems today is that no one is taught our history any longer, or where our civilization came from. Erase the past, and brainwash the peons.
The thing is that these guys are being relegated to part-time status with no hope of tenure or decent pay. The permanent faculty who treat them like this probably specialize in gender-bending and mind-washing, and won’t give these guys a chance at tenure because they’re too conservative and insufficiently politically correct.
Please stop making sense.
It's not the permanent faculty who don't want to give the temporary people a chance--it's the administration which decides when a department can hire a new tenure-track person, and administrators have discovered that it is cheaper to have temporary and part-time people doing a lot of the teaching.
