What is your culture? America is a melting pot of many different cultures. One dominant culture, and many sub-cultures. When the dominant culture is not curtailed we see all sorts of problems, which academia has enumerated. So the dominant people in the dominant culture feel powerless. Because when they are not in this position, according to academia, bad things happen. Take that how you want to take it. Governments are okay with this because they want to dis-empower people, in order to control and manage them better, and this is but one way of doing that.
