no, what I am saying is that there are some situations, for instance GIVING A SPEECH, where people ought to be able to be heard
Okay. I can't tell, however, whether you think this is a privilege or a right, or (as a corollary) if your objection is about manners, political strategy, ethics, morals, or legality. I agree, for instance, that it was impolite (but not quite as impolite as, say, hunting down people) but not that it was immoral.
Really, I'm not so sure that "giving a speech" is a narrow enough metric. Should anyone be allowed to give any speech? And at any private place? And if you disagree with the content of a speech, what forms of protest are available to you? What if you will be prevented from bringing in banners or from joining the Q&A or even from attending (as in many politicians' speeches)?
Is it the special character of the university campus that makes the protest so troublesome to you? (Do you think this bears on academic freedom? I don't, but it's a better argument than the one that rests on free speech in my eyes.) If the speech had been at a church or a private foundation or a museum or a private home, would you be upset in the same way? What if Columbia had said no to the College Republicans bringing Gilchrist to speak?
umm, no one is saying that people ought to be allowed to speak anywhere they please. I am saying that if I invite a speaker and a bunch of people to listen to him on MY property, and the audience shouts him down, that that is not only bad manners but that it shows a lack of respect for free speech on behalf of the shouters, not the least because this particular place this guy was invited to speak was devoted to free speech. further columbia would have been completely within their rights to throw these people out and arrest them for trespassing on the stage
