 We are living in history. We are not at the end of it. And history shows us very clearly that when political tensions eventually lead to political assassination attempts, things don't just stop there. The tide doesn't come to a screeching halt. The factions don't pull up short and say, oh, geez, maybe this has gone a little too far, guys. That's not the way this has ever worked. And we are not history's great exceptions. It's high time we admit that to ourselves.
