I've often seen academics in the history related blogosphere poo-poo the idea of political correctness and mock those who bring it up as a problem. I think this is most often due to the fact that they are complicit - or fearful. At best, they are out of touch with most Americans:
"A new Rasmussen Reports national telephone survey finds that 57% of Adults believe America today has become too politically correct, while just 23% say the country is not politically correct enough. Eleven percent (11%) say the balance is about right. Some people think that government officials too often override the facts and common sense in the name of political correctness, and 74% regard political correctness as a problem in America today."
