JWC, you have a good point about the "default right" thing, but I need to bring this up.
When the Constitution was written, everyone had muzzle-loading muskets! The tech of the day was very low, like a gunpowder BB gun. I don't know if the framers had today's society in mind. It was written when we just became a country, and they were thinking about what things they didn't like about England and how not to become them. (Even though we slowly are in more ways than one... *coughchurchandstatecough*) In the time, we were fighting for freedom, so they wanted to make sure that if someone tried to attack them, everyone was ready.
I believe that gun ownership IS an individual right, but the intent of the framers is lost in today's society. We don't need the Minutemen anymore. But regardless, gun ownership is a right that can't be taken away without an amendment altering the 2nd Amendment.
I'm an airgun owner, Democrat, Constitutionalist, supporter of rights, but not NRA material. I know very well what inalienable rights we as Americans have, and speak out for them. I speak out strongly against Prop 8 and directly quote the Constitution, for example, but that's as far as I'll go on that topic in this thread.
