The rhetoric of fear and abuse of hyperbole some to mind. The latter is evident in your very comment.
I'd like to digress from the main topic for just a second and just explore this point a bit.
When I said that millennials don't generally respect freedom of speech, let me expand a bit on that.
First off, this is a generalization. I don't need to explain what that is.
Second, I have no doubt that millennials care about freedom of speech when it pertains to their own views. So they would be angered at, say, a Bernie Sanders rally being shut down by right-leaning business interests. However, as I'm sure you agree - free speech is, by definition, the belief that
opposing viewpoints have the right to speak as well as agreeing ones. In the entire history of humanity, no group has ever called for censorship of views that group agrees with. Everyone, everywhere, certainly agrees with their own right to free speech or the rights of like minded individuals. Free speech must, by definition, embrace controversial, even offensive views, or it's a nullity, end of story.
Third, and most significantly - I put it to you that the majority of any large heterogeneous group, anywhere, by default, is going to be politically neutral or apathetic. The vast majority of humanity is apolitical insofar as they just want to get along with their lives, do their jobs, raise their families and attend classes. They want to eat, screw and work in peace. That has not changed with the millennials. By definition, most of them don't care much one way or another about free speech on any practical level, although they may have some vague sensibility about it that they'd share if you pressed them. So to point out that the majority of millennials might not embrace certain views or seek to actively campaign would be true, but would certainly eschew
any attempt at commentary on the political makeup of a generational group.
Therefore, the only people we really care about when we're making a generalization about the ideological flavour of a certain generation, is the political class, the activist class, the group that really does care and is willing to make their views known.
I believe the evidence has been growing that this group either outwardly reviles free speech, seeing it as an instrument of systemic oppression and the reinforcement of various forms of privilege, or (among those who are without much intelligence or possessing a high degree of cognitive dissonance) thinks that they believe in free speech, though the evidence is overwhelming to the contrary.
I can provide links to various stories of late, one recent example being the campaign to extinguish pro life advocacy from campus life through various means, whether brownshirting pro life speakers / meetings, or (in a recent example) making the cost of security so high that it is financially prohibitive for any pro life group to organize on campus (in the University of Alberta case, the university was going to charge the pro life campus group $17,000 in security fees in anticipation of its rally, which of course it could not afford.) There are other numerous examples, such as groups lobbying to ban right wing speakers (Ann Coulter, George W. Bush etc...) student unions refusing to authorize resources for non approved groups (most recently, a pro Israel human rights group seeking to have a booth at a social justice rally in an Oshawa university).
I don't believe that these are just isolated one offs. I happen to think that this sort of mentality, and the mentality of the young man who commented that he wanted to "shut down" Trump's event are exceptional or the behaviour of one-off thugs a la Cowboy Man. This is going to be the new normal.
Now it's true, as some will point out, that many have always practiced such tactics, but the difference is: if you go back even to when I was in school (I am a tail end Gen Xer) if someone put Voltaire to the class, everyone (even among the political class) would have agreed, at least in principle. Free speech was a value, even not everyone actually implemented it in practice. I don't actually think free speech is a value in any meaningful sense for millennials, among the group that matters. It has been supplanted by other values which can't co-exist with it.
