I see someone printed the university's conduct code, as if the simple fact a state law or regulation existed were proof of its constitutionality. But thousands of such laws and regulations have been struck down as unconstitutional. I don't say this one is, but the Supreme Court protects the freedom of speech about as strongly as anything in the Constitution. Having a free country means letting people say hateful and repugnant things--in fact the Court has observed that it is exactly the most unpopular speech that calls for the greatest protection. In this country, we don't rush to the rescue every time some delicate flower points his finger and wails, through his tears, that the bad man said mean things that made him feel all icky. The world is not a kindergarten, however much faux liberals would like to make it one.
