In a properly functioning America like the Founders envisioned, a repeal of the Second Amendment would be virtually meaningless. The right existed already; the Constitution merely secures it. Unfortunately, our society has loosened its grasp on natural rights philosophy and devolved into dependency on government-sanctioned rules. Today, however, even unambiguous text is under scrutiny by Democrats as prominent as former Supreme Court Justice John Paul Stevens.
Same thing for my right to free speech and religion. They are to some extent protected by our government, but not granted by our government. Do Saudis and North Koreans have less of a free speech and religious choice right? No.
It used to be that the left cared about human rights everywhere. Now, not so much.
