I don't know if there are a lot more murders, but since the middle of Obama's time to now, I've seen politics have more families spending less time together, people with friends on Facebook getting into ridiculous battles to the point of ending friendships, and I don't know if you've noticed but if someone doesn't take a real stand against Antifa and Alt-Right, a civil war isn't the craziest idea.
It won't be north and south, though. It'll be left and right, and it will end quickly because, let's face it, you should never bring a gay couple looking for a wedding cake to a gun fight.
