I'm talking here about the alt-right, e.g. Milo Yiannopoulos' crowd, who self-profess that this was partly why they voted for Trump. People for whom this election was largely cultural, and saw Trump as a "fuck you" to the safe-space, microaggression, language-policing left.
I know they have real concerns, like economic pain, threats to their way of life, and concerns about mass immigration—concerns which, by the way, I argued in the grandparent that the left counters with labels. "Your concerns aren't real; you're just xenophobic." But I think the cultural stuff was a big part of it.
I realize they don't represent all Trump supporters, and never said they did.
