I think I've underestimated this. The thing is, even a small number can cause a LOT of issues. A small number can also create a lot of good things.

Good point. That kind of thing has certainly been rampant for about the past decade and it has revolved around partisan politics.

Maybe the scale of violence also changes. 

Rather than national-scale armies of young, fit soldiers going to war, a significant rise in petty crime (vandalizing statues, stealing from stores, other destruction of property, etc…) from the most extreme 1% of each political party

Just thinking about America, my sense is that people are too fat, sick, lazy, comfortable, and weak to engage in widespread violence.
