Alexander Hamilton: "The best we can hope for concerning the people at large is that they be properly armed," adding later, "If the representatives of the people betray their constituents, there is then no recourse left but in the exertion of that original right of self-defense which is paramount to all positive forms of government." By the way, Hamilton is referring to what institution when he says "the representatives of the people"?
James Madison: "(The Constitution preserves) the advantage of being armed, which the Americans possess over the people of almost every other nation ... (where) the governments are afraid to trust the people with arms."
Thomas Jefferson: "What country can preserve its liberties if its rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms."
George Mason, author of the Virginia Bill of Rights, which inspired our Constitution's Bill of Rights, said, "To disarm the people -- that was the best and most effectual way to enslave them."
Rep. John Lewis and like-minded people might dismiss these thoughts by saying the founders were racist anyway. Here's a more recent quote from a card-carrying liberal, the late Vice President Hubert H. Humphrey: "Certainly, one of the chief guarantees of freedom under any government, no matter how popular and respected, is the right of the citizen to keep and bear arms. ... The right of the citizen to bear arms is just one guarantee against arbitrary government, one more safeguard against the tyranny which now appears remote in America but which historically has proven to be always possible." I have many other Second Amendment references at http://econfaculty.gmu.edu/wew/quotes.html.
How about a couple of quotations with which Rep. Lewis and others might agree? "Armas para que?" (translated: "Guns, for what?") by Fidel Castro. There's a more famous one: "The most foolish mistake we could possibly make would be to allow the subject races to possess arms. History shows that all conquerors who have allowed their subject races to carry arms have prepared their own downfall by so doing." That was Adolf Hitler.
