"University of South Carolina joins the mob"

How? Well, a student was suspended for usage of a racial slur on a dry erase board in a study hall. I don't think suspension appropriate, but am tired of this rhetoric. And, I think the professor is being a bit of a jerk. If the 1A compels not allowing public universities to set up minimum politeness rules even in study halls, fine. It still is not a "mob" action "silencing" debate. And, note not only can't the "n" word politely be cited there, nor is it simply treated the same as the general idea in 1A law, but being honest leads to him sounding like a baby.
