In my mind, and correct me if I am wrong, the best solution is to just confront individuals themselves. Are you being racist or discriminatory on our campus? You're out. Set up a system that makes it easier than ever to report hate crimes or racial actions. Invoke the hardest punishments possible on racist students. No tolerance. In that way, it should set up an example for future generations of students. They can see that if you say something bad here, you're out, no questions asked.

Im not sure you really thought this one though. Who decides what racism is? What is hate speech? There is a real big trend out there to try to subdue "wrong" speech but who gets to decide what wrong speech is? Is being against illegal immigration racist? Some people like to claim it is. Is advocating for weight loss hate speech? Some might argue it is. Many argue that advocating for mens rights is sexist. Should we ban all those people from universities?

Even in extremes lets say someone comes from a real hole in the wall area and hates blacks and gays. If you ban that person from the university that person well never have a chance to change their views and become enlightened. Banning that person will only strengthen their hatred and in my mind is counter productive. Its better to have that person speak their mind and be corrected than it is to have them keep the quite hate in.
