I've thought about this a lot over the years, since Escalator Day™.
Trumpism is largely a response/reaction to the Left's weaponization of PC/Identity Politics that started with Obama's first win. I spent my first few years here squabbling with the Left over this, telling them that they were going too far and that there would be a pushback. For that, of course, I was called every name in the book.
Resentment on the Right had risen to a fever pitch, and then Trump comes along to shamelessly supercharge it. He lit a fuse that was primed and ready to go. And because the Right is so conditioned to the comical hyperbole of Talk Radio, they've taken what the Left was doing, reversed it, and multiplied it by a hundred.
So now, MAGA is doing exactly what the Left did -- they're going too far too fast, and the resentment in the opposite direction is rising just like before. The ends of the spectrum
just do not learn.
