Is it bad that I'm not surprised by this? Or the fact that I'm kind of in the 50% that can see it coming.
Maybe I'm too naive, but I feel absolutely no need nor desire to act violent towards my fellow Americans. I feel the divineness growing, I don't know what a "civil war" would actually look like. It seems like most Americans already live in bubbles where most people are aligned politically, so who are they going to fight?
We're not.
The most likely geographic split would be urban/rural, cities against everyone else. Around half the population is tightly concentrated and align mostly with the Democrats, the rest are spread out and align mostly with Republicans. Even blue states are mostly red outside of cities.
For just one example of something that could spark it, the current hot topic of abortion access: the often-disregarded side sees abortion as killing babies, not even close to how the other side sees it. With that viewpoint and tensions rising in general, how long do you expect such a huge number of people to simply endure?
