That's not true at all.Typical reaction, it only matters if it happens to you.
I was recently lambasted by one of my friends who is an advocate of carrying when ever allowed. He went so far as to say I'm foolish, reckless, and destined to be the target of some violent exchange ending in my demise. He said, "If you don't protect yourself, you'll die." I asked him if he had a carbon monoxide detector in his house. He said no. Never mind that 6,000 people have died of carbon monoxide poisoning in the last ten years. I asked if he had airbags in his '78 FJ, which of course he doesn't. He's simply choosing to place importance on certain potential dangers, which we all do, and it's perfectly okay.
Everyone makes choices relative to their defense against certain perceived dangers. Choosing to not place a life threatening violent encounter as high on your individual list of concerns somewhat falls in line with many other life choices.
