Racist college professors

Damon Sajnani will be teaching a class at the University of Wisconsin at Madison this next semester which in the overview of the class implies that all white people are racist. If someone tried to put a class into any college in the nation which described itself as intended to explore the racist black population in America, they would be run out of the town on a rail, and justly so. However, in the super 'liberal' colleges it appears that anyone can call any white person a racist or make racial slurs against whites with impunity. I am disgusted with the blatant double standard that is constantly applied. Whites can be demeaned but not even a whisper about racist blacks is allowed.
