I very recently graduated from a college where these activists were very active. I can assure you, that there is not some epidemic of racism or any other kind of discrimination that this is a legitimate reaction to. It's nothing short of a political power-grab and an attempt to shut down any discussion by people that they don't agree with. They have successfully created a climate of fear. The reaction among all of the different institutions--different academic and administrative departments, student groups, greek organizations, alumni groups, etc.--is nothing short of race to capitulate the fastest.
