This problem can cut both ways. Ie. if one dismisses the other person as the political equivalent of a "flat earther," they're not questioning their own assumptions or seeking to understand why the other person could feel something so strongly.
Having lived in both deeply red and deeply blue states in the US, I think most people aren't as crazy or as far apart as they think they are. But many of the people who have lived their whole life in one camp have been trained to think that the other side is literally crazy, and that's a convenient excuse to be afraid of them and not bother seeking to understand them.
