Hmm,<p>Universities have <i>traditionally</i> had codes of conduct. They weren't invented by pot-smoking hippies.<p>Tenure is based on the idea that after working like a dog and reaching to top of your field, you should <i>then</i> get an unrestricted forum to express yourself - you've earned it.<p>The examples of someone being falsely accused and convicted of racial harassment don't prove that students should be able to shout racist and sexist slogans whenever they want. It shows that universities should correctly aply statutes against harassment in a reasonably limited fashion.<p>So, of course, universities <i>should</i> restrict some speech. They certainly go overboard in some cases but that's a different matter.
