Even avon ladies and mary kay moms have been known to be some really sick individuals.
Didn't a cheerleader's mother murder a competitor a few years back?
It's unfortunate that a lot of low IQ mouthbreathers and mentally ill are drawn to the act of shooting. Lound noises, big stimulation, lots of neat, shiny toys, and things that go boom and are scary. Killing animals is a lot of fun for some people, and if you can do it with a big loud gun and make a big mess it's better than wrapping kittens in duct tape, as you might be bitten or scratched when you do that.
I mostly see real gentlemen carrying arms, as I use clubs, and public ranges around lifetime shooters who are former miltiary and such. The rudest thing I've ever seen was for a range officer to berate a punk for a grievious breach of rules.
