yes, I think his book "Reamde" had the concept of "Ameristan" which was the redneck-Idaho equivalent of many racial/religious/socioecon tropes.
If the "Right/Left" or "Liberal/Conservative" is too hot button for any kind of discussion.
He also wrote "Anathem"
Which is fictional world, with fictional sides, that can be used to explore similar concepts a little less triggering.
