One of the most lucid and clear statements on the 2nd amendment I’ve seen in recent history is in an article on the site Center for a Just Society. I quote a small part here:

Simply put: “The right [not privilege, right, just like freedom of religion, speech, the press, and assembly are rights] of the people [the American populous; we really didn't need the Supreme Court to tell us that this summer to know it was so, but they reaffirmed it anyway in the Heller decision] to keep [own and keep in our homes] and bear [carry about as we determine necessary for our security] arms [guns, knives, swords, battle axes, etc.) shall not be infringed [government won't even come near to touching it; won't touch the "fringes" of it].”

We should not put up with the legislature taking away our rights. There is no “common sense” restrictions on guns for law-abiding citizens. Tell your congressman and senators that you want them to vigorously fight to restore what the constitution says in regard to guns: that the right of the people to keep and carry with them the arms (weapons) for self-defense are beyond the control of the government.

It is a right, not a privilege, and the government does not have the authority to infringe it.
