What do you think?

I firmly believe that there should be free speech for all, even those we do not agree with. I was reading this brief article about a student at a community college in Los Angeles who was berated by a professor for their stand on gay marriage. I saw the title and thought it was about a person who was pro-gay marriage, well I was wrong. The student gave a presentation about the fact that he thinks gay marriage is wrong. As you can see from my side bar, I am on the other side of him. I think that everyone has the right to get married and that there is no reason that the government should be involved in who and who cannot get married, but this student also has a right to his opinion. According to the article, the student says that midway through his speech he was cut off and called a "fascist bastard". And when the professor returned the grading rubric, rather than giving a grade he wrote "ask God what your grade is." Now maybe the student was blatantly hateful in his speech, but the article, of course, does not give us enough information to make a determination either way. So I have to go on that the professor reacted badly to the speech, by being childish by getting into a fight with a student and then refusing to give a grade. If the professor did not feel that the sources used were appropriate or that the student was being hateful or that the student was not respectful of others than there are ways to handle that, but to act childish is not one of those ways. I also hate the fact that this professor gives all liberal a bad name and just supports the whole notion that liberals are unfair to the opposition and unreasonable.

So my question is, if you are/were a college professor and a student wrote a paper or gave as speech and it was in direct opposition to your opinion on the topic, how would you handle it? The caveat I am going to add is that the student is not hateful toward you or other students, but has an opinion that may be unpopular or antithetical to your own.
