Professor Swain, Vanderbilt and expressing a view

Students at Vanderbilt University are targeting Carol Swain, a professor of law and politics at Vanderbilt (and a member of the James Madison Society, of which I also am a member), because she has criticized Islam — in other words, because she has her own views on matters of civic importance.
I do not share Professor Swain's view that Islam itself is the problem. It seems to me that many Muslims disagree with the peculiar jurisprudence of Al-Qaeda and ISIS supporters, and I am not in a position to discern which groups or individuals have the best interpretations of the Koran and Hadith. So, I am not prepared to paint with as broad a brush as Professor Swain uses. But it doesn't matter whether I agree with her. She is a reasonable, accomplished scholar expressing a view that reasonable people hold. And even if I thought her view were unreasonable, she has a right to express it as long as it does not amount to defamation or some other legally-cognizable harm.
