Yes, but people are allowed to do that. I don't think "free speech" means what you think it means. It's a comforting idea that other people are too immature/emotional/dumb to consciously think about an opposing belief, but that wasn't the case here. There's no obligation to hear out a side that would do you harm given the choice. w/r/t letting people say unpopular things, the university did decide to host him in the first place, which represents the university's commitment to some form of free speech. Individual people should not be subject to scrutiny for protesting something they disagree with.
Calling me names (or other people) doesn't make what you're saying valid. It wasn't an effective tactic for the left during the election and it's not an effective tactic in this conversation.
At any rate, I don't think you're arguing against points that I've actually made. This sounds more like a response to some hypothetical response that you were anticipating before I responded.
Is your intent here to justify the existence of this watch list?
The first amendment lists a specific purpose for free speech - for the public to redress grievances to the government.
Do you not think that this watch list will curtail free speech infinitely more than what you're complaining about? By monitoring protests and reporting legal political action to employees, you can implicit discourage political protest - which IS a legally protected form of free speech.
