In my school years I had extremely low tolerance for un-courteous, incompetent, or otherwise dumbass teachers. I was heavily instrumental in “retiring” at least two of them. Even if I wasn’t the one being mis-treated I took it “personal” and quietly worked to make their own lives somewhat miserable. Maybe I’m an exception but I truly don’t understand students taking cheap krap from teachers. For that matter I don’t understand taking cheap krap from a boss——there are endless ways to make it come out “even”.
I just finished putting three members of family through college. For the most part they were afraid of taking on professors because they could just arbitrarily issue a failing grade and then it is start over. At 25K per degree (local college) you don’t want to start over. College actually makes more $$ on the ones who fail as they collect up front, no refund if you fail. 95% commie professors who preach their liberal politics to their classroom and don’t teach the material. These professors are scum.
