Folks collect all kinds of cool stuff. Sometimes their collections are firearms. It's a hobby; like with other hobbies, a person can get a little carried away. The whole 'self-defense' industry needs firearms hobbyists to get carried away in order to sell more stuff.

Some people really need a firearm in order to stay alive. Nearly all firearms owners don't; it's instead our right and our hobby - trying to make it into something else is nonsense. Or fantasy.
