Convenient shorthand for a huge number of issues. OK then, how about convincing them to support:

- impeachment and prosecution for high level corruption (e.g. the Presidential cryptocurrency)

- prosecution of constitution-violating police and Federal paramilitaries, e.g. in Minnesota?

- leaving LGBT people alone legislatively (at this point I'm not going to ask for improvements, just that the situation not be made worse)

Ok, let's talk about identity politics. It started with people bringing their religion in to their lawmaking. Let's ditch that first and see what else we need to do.

This is a lot of it. Urban liberals see rural working class as backward and racist and uncultured. Just having a non-coastal accent (eg southerners) is treated as a marker of low character in our media. I recall how GW Bush’s accent was treated, as do many rural voters. Look at the discussion here, it’s about “those people” being too dumb to vote for their own interests. Unsurprisingly, people resent that.
