And the vast majority of those blue residents aren't going to loot, just as the vast majority of red ones aren't going to rise up in violent protest. In both cases we're talking about a subset of the population. The main difference, however, is that it doesn't seem like most of the blue looters were really politically motivated, outside a few agitators. The small subset on the right, however, are very politically motivated.
I guess what I'm saying is, if we're specifically talking about a reaction to an unfavorable election outcome, I'd be much more worried about a Charlottesville than a Minneapolis.
