Some valid points here.

If you'll forgive me a moment of insufferable self-promotion, I have a suspicion you'd enjoy my novel Peaceful Quiet Lives - a satirical dystopian romance set in a future post-Second Civil War US. It satirises the worst fears of both sides of the polarised culture wars, and the kinds of us-or-them extremism you discuss here.

Here's the novel if you're interested: https://www.amazon.com/Peaceful-Quiet-Lives-Simon-Dillon-ebook/dp/B08PC1JCXL
