I’m afraid so. There are a lot of people still fighting our Civil War, the one that supposedly ended over 150 years ago. Even without those troglodytes, there is a distinct cultural difference between the North and South, as I think there is in many countries. We tend to rub each other the wrong way sometimes.
Old joke about the difference. Walk up to a Southerner’s house, and they say, “can I help you?” Walk up to a Yankee’s house, and it’s, “whaddya want?”
There was a bomber in Texas who murdered several strangers with package bombs left on their doorsteps. He blew himself up just before he was captured. I don’t think we ever got an explanation of his motivation. It’s really rare, but it does happen.
The fact is that most of us are alive simply because no one has decided to kill us yet. There is no complete safety in this life, so you may as well take reasonable precautions and chill. Enjoy your life.
