tl;dr: Censorship is wrong.
First, no one's free speech was violated. The First Amendment prohibits the making of a law to inhibit free speech. It doesn't matter who funded the school, it was not a First Amendment violation. The Mizzou incident, however, may be considered assault, depending on the interpretation (IANAL.). The students had the right to assemble, not to go after the reporter.
I consider the Bill of Rights to be sacred. I don't necessarily agree with all the interpretations of it, but it forms the basis for a civilized society. Among those ten amendments, I consider the First to be the most significant (followed closely by 4-6). We are not a society that censors. If students want to assemble and protest, they have every right to do so. But that journalist has a right to be there.
I am a Penn grad and was at the school during the "water buffalo" incident:https://en.wikipedia.org/wiki/Water_buffalo_incident
To say that it was embarrassing is an understatement. It was humiliating that a top liberal arts school not only "prosecuted" a student because they didn't like what he said but also that he faced such a kangaroo court. If he hadn't had Alan Kors, one of the top professors at the university, to defend him, I don't know what would have happened.
Side note: The student involved ran for student government the next year by plastering the ridiculous letter that the administration had sent him all over campus. He won.
I don't like a lot of what people say. I've listened (and responded to) antisemitic, racist, homophobic etc. speech. I find it hateful. But I would never deny anyone the right to make that speech. I'm a liberal Jew. Did I like the fact that the KKK could march in Skokie? Absolutely not. Did the ACLU do the right thing by defending them? Absolutely. The best thing that Skokie could do would be to rally citizens against the hateful speech and show the numbers of those who opposed the KKK.
Oh, on Israel, since that seems to be where we've gone: I'm a strong supporter of Israel, but when I hear things like people saying that criticism of Israel (or any other country) shouldn't be allowed, I get very, very nervous.
Bottom Line: Speech is powerful, but our right to use it is even greater. And it's shameful that a new wave of censorship is coming from universities. Those students should be out there protesting to maintain their rights, not shut them down.
In any case, to those of you who have made it this far, thank you for reading.
