No it isn't. If you really want to see fascism in the US you have to go to college campuses, where students are expected to shout down speakers and assault them.
You're right and wrong. To the extent that such suppression is happening on campuses that is also an example, but it doesn't excuse Trump. Your argument amounts to "but those people are also a-holes!" Well okay, sure, but yeah.
That's why I included left-populism in my top level comment. Populism tends toward authoritarianism and... authoritarianism is authoritarianism. The extreme left and the extreme right converge on very similar things. In both cases you get a lot of "the end justifies the means" and we know where that goes.
