Why waste time and/or energy fretting over the guy's attitudes? Good grief, some folks can't be helped, don't want to be helped, and apparently believe that they don't need to be helped. Fine. Let this bozo simmer in his own stew, and good luck to him. If he makes it through life with an incident or accident, good for him. If he doesn't, he only has himself to blame.
It's my view that we in the gun community spent far too much time worrying about people who can't be changed or persuaded and who don't want to be changed or persuaded. We should spend our time and energy instead on those who can be changed or persuaded, or on those who truly matter in the fight: legislators, jurists, policy-makers.
