Yes, the response is visceral. There's no critical thought. Jobs, trade, "economic anxiety", all of that is used after the fact to justify their visceral/racist response to "those people." They don't want to think of themselves as racist and know that it isn't socially acceptable, so they find means to justify why they feel the way they do.

The justification follows the racism, not the other way around. As I said, the disagreement over what transcends what is really the crucial piece in this discussion.

As I said, the "working class whites"/economic messaging/dismissal of "identity politics" and political correctness narrative is being promoted by leftists, centrists and Trump supporters. It's the same narrative coming from different angles/spins; I'm not saying Sanders is promoting the same policies as Bill Clinton did.

Which reminds me, regarding political correctness, what I was saying earlier is that term is used by many to be dismissive of what is really just basic decency. It's not political correctness that says you shouldn't be a racist, misogynistic asshole. It's human decency that says that. When Megyn Kelly read those quotes of Trump's regarding women, he and his supporters dismissed objections as "political correctness run amok."
