I saw a blog article in which a man who always travels with a firearm came to realize that he no longer was disturbed when engraged weenies yell or honk or throw gestures to him. It's as though the realization that the man can instantly evaporate any human at will, makes the game more serious, the man more serious, and the weenies more inconsequential.
It's an idea that hadn't had currency, or at least visibility, before as far as I know. But, the responses in the comments alley were a long list of men and women who've had the exact same experience. When they're packing, life is more serious -- and noxious but trivial people are just all the more trivial.
