You are correct. Of course, it's much more complicated than that. It's not EXACTLY white males who are the ones feeling so alienated. And the extremist social justice movement is a minority that rarely touches older white men (and old people are the ones who handed Trump this election), but it is an extension of broader movements like modern-day feminism, classism, elitism, etc. As Louis CK put it, "'I saw this guy the other day, he was white trash--' 'Oh, fuck that guy!'" Your article is a microcosm of what Glenn Greenwald (you'll remember he was the journalist Edward Snowden chose to release his NSA information to) discusses at length here, and you will see echoes of your words in it: https://theintercept.com/2016/11/09/democrats-trump-and-the-ongoing-dangerous-refusal-to-learn-the-lesson-of-brexit/
