I think about the only speech that should be 'banned' should be speech akin to shouting 'Fire!' in a theater when there is no such fire.
Speech that offends, insults, slurs, or otherwise makes people uncomfortable or angry is just fine with me.
Many people are just crying out to be offended. Some are sincerely offended, while others pretend to be so in attempts to control others.
Either way, it does not matter - their feelings are not relevant. Neither are mine.
I don't think that swearing, hate speech, offensive speech, 'blasphemy', obscenity, etc. should be against the law or against college or university regulations.
It is far more important that free speech be protected than that people not be offended.
