A couple of weeks ago, Diane Singer posted an article about a professor's abuse of power. Unfortunately, the situation is not uncommon. 

In the September 6/13, 2008, issue of World magazine, Ed Veith has an article about the late Richard Rorty, who admitted to conspirator-type teaching tactics. Rorty openly stated that his intent was to ridicule  "fundamentalist parents," to whom he said, "We are going to go right on trying to discredit you in the eyes of your children." 

Rorty even compared himself to Nazi teachers, with the difference being that "I serve a better cause."
