That's a mouthful there, isn't it? Not just the gun culture fits it, but many other things as well: Nationalism, Materialism, Capitalism, etc. come immediately to mind.
By the way, there's a good post about how guns make you stupid. This post is by an expert marksman and former Army counter-terrorism guy, so he knows of what he speaks. Give it a read; here's a snippet to whet your appetite:
As someone who used to carry, I can say that - when I was armed - I would go anywhere I wanted, whenever I wanted, respond to anyone any way I wanted, be as rude as I wanted, as inconsiderate as I wanted, and meet those little non-verbal challenges that strange men throw at each other because it's a man-thing any way I wanted, and respond to rudeness and idiocy (to which I could choose not to respond) . . . because I could. There it is! The criterion for stupid. I have a damn gun, and I know how to use it. I can put two rounds in your thorax in less than a second. I can erase you.With thanks to Jim Eisenbraun for the link.
I used to claim it was for self-defense; but for quite a few years now, I've gone unarmed and miraculously survived. I do avoid certain people and places, i.e., drunk people (the most dangerous of animals) and places with a lot of drunk people. These were the people and places that most often put me at risk back in the day. I don't do that any more just 'because I can.' I am also deferential, courteous, and friendly (when possible) with strangers; I don't do the dominator-stare-down thing with other men. Common decency/common sense stuff, that you can abandon - stupidly - when you pack heat. (emphasis original)
