Can't read at the moment but is this the piece that blames gay people for not being more magnanimous in their recent victories?
So the article has several flaws and you've touched on one of them (and I'm well aware that the fact that the author is
Andrew Sullivan doesn't make that statement forgivable.) I think his basic premises are sound, though:
1- Trump is a classic demagogue that our democracy is poorly equipped to handle, especially in an age of social media.
2 - He is exploiting very deep resentment which is felt among a large segment of the population, and it isn't clear that the Democratic establishment is prepared to deal with that over the long term.
3 - Even if Trump himself is unelectable, the dangers of "Trumpism" - open xenophobia, embrace of ignorance, disdain for facts, and threats of violence - are being underestimated, and the sooner he is dispatched the better. I don't think he will be any more gracious in defeat in November than he will be if he loses at the convention in July. It might be better to for us to have him lose there, throw a tantrum, and watch Cruz go down in flames in the fall.
-"Identity politics" do not empower Trump. The fact that white people in America are super fucking racist is what powers Trump.
I think you are understating how closely related these two things are.
