I don't think we should ban guns or anything, but calling it a liberty issue is quite a stretch IMO. The real, core, liberties are all about protecting the free flow and expression of ideas. Free speech is precisely that, but the right of association, due process, freedom of religion, equal protection, etc, are all there to enable the development, free exchange, and protection of ideas. The right to bear arms used to be about that too back in the day. It was a check on government. But today it has lost that element completely. Now it just seems to be about people think guys are cool... So, I don't think we should ban them or something, but I think it's pretty grandiose to still be canonizing the right to bear arms along with the more serious rights.
