I appreciate the data! However on the second point, I will note that I don't know of any term used recently by rural communities to describe urban dwelling. City Slickers being the only term that I know but have never heard or seen written in news.

"Flyover Country" is thrown about often however. Especially around election time and regarding how they are controlling to much of the country's politics.

I'm not sure it's proper to conflate flyover vs. coastal states with rural vs. urban. Even the middle-most states of the continent are majority urban dwellers. Most people in Kansas live in either KC or Wichita. The only state that is really majority rural is Vermont.

I disagree.

1. Those who express disparaging remarks towards others do not need to utilize a specific term.

2. A common narrative is that urban environments/cities are mismanaged, possess dangerous amounts of crime, and filled of corrupt politicians.

3. "Flyover Country", in a political context, is generally a complaint about the structure of representation.

Flyover country just alludes to the reality that people from the coasts don't go to places like Kansas for vacation or really much reason at all.

"coastal elite" I guess. The entire trumpist movement is built on the back of negative feelings toward urban dwellers.

That second source doesn't support what you said at all. I think you need to reread it. The conclusion I'm getting from it is that people, regardless of where they are from generally think the same about people from other areas. They assume they are able to understand other's situations but don't think others are able to understand theirs's.

The contempt rural people have for urban dwellers is palpable if you ever spend any substantial time with them. God forbid if you’re from California cause then you might as well be Satan’s spawn come to harvest their children for adrenochrome.

In cities, not one single person has ever felt the need to stop their vehicle, roll down their window, and shout a homophobic epithet at me. Outside of cities, this seems to happen regularly.

When a rural person comes to town, do the local urban people take a moment to shout something derogatory at them? If that happens I have never seen it.
