The University of North Carolina at Chapel Hill "Welcome Wagon" lost all its wheels last night when former Colorado congressman Tom Tancredo attempted to speak in a university classroom and was silenced by protesters and essentially run out of the building. A window was broken. Pepper spray was used by the campus police. Bad, bad scene.There's finger-wagging going on this morning at that campus, and many people obviously need to feel ashamed. That was not the way to respond to a different opinion.
