I too believe it is a fundamental right that every American can exercise if they choose to. I personally don't own a gun. My dad actually taught my sister and I how to shoot a riffle when we were still in elementary school. If you hand me a loaded riffle, I can shoot it and probably hit my target (if it isn't moving or too far away) but I have no idea how to maintain said firearm.
I know there are a lot of people that don't agree with the whole "right to bear arms" thing, but it really is a big deal here. Actually, its part of our culture, you know that whole hunting and fishing sportsman culture thing. Its a huge industry representing millions, if not billions of dollars in annual revenue.
Right now, there is a survivalist movement going on here. I think this whole "right to bear arms" is at the core of it.
