The offended tend to argue about speech as though it is all functionally and legally identical.  Using a university's internal resources, e.g. a web site, to express a viewpoint is not the same as expressing that view in a loud voice on the sidewalk or in a milder voice in the classroom.  Context matters.  

Using the N-word in a class discussion of Huckleberry Finn is essential. It is impossible to excise one scene, in which a white woman expresses her pleasure that no one was hurt because only a negro was killed, and still teach Twain in a meaningful way, because the specific words are crucial to his way of pointing out hypocrisy. Using the same word out on the street in the face of a black person has no such purpose. 

Most universities are run by the fearful today, and college leaders are unwilling to move slowly and carefully in responding to speech problems case-by-case in the face of political noise.  They instantly go to SweatCon 4 and flail about.  The result is usually bad.
