I hear this rubbish all the time, but the Federal Government is doing things that George III would have blushed at, yet there is no armed revolt in the streets. The reason being, things overall are pretty good, and the people who did take up arms in Montana or Waco got shot by the FBI. The right to bear a rifle or handgun in this context means very little - if you said that you wanted it for personal protection against criminals, that I would understand. But then again that reason would seem not particularly great against terrorists. As for the threat of being killed by terrorists, the vast majority of people in the urban United States don't share your attitude, I dare say. September 11th taught a big lesson - if you want to be ignorant and forget it, that's not my problem.

As I said earlier, our core philosophies on the RKBA are 180 different. Neither of us is going to convince the other. I would also recommend that you search FR's archives for Waco threads if you think the FBI was in the right there.
