So people want guns because they feel mortally threatened by the things out there in the world. They want the guns so they can defend themselves. They have this notion of defending themselves because they believe they are someone worth defending, worth keeping around - of value to the world. They're willing to stand up and fight and, quite possibly, kill in order to maintain their place in the world.
Yet I can't help but think of how these sorts of gun-stroking citizens really do nothing remarkable for the world around them. They're so far up in their ego-worship that they believe they're of such uber-importance that they've gone around the bend and now think that everyone else either wants what they have, or is willing to jealously harm them because of what they have (and these less-thans, presumably, don't have).
Also, I imagine these people's thoughts being comprised of nothing more than a Gregorian chant of fart noises.
