The means to protect our liberty are the vote and the constitution.
Guns are for the thugs who can't get their way except by violence. I happen to own legally registered firearms myself, and I learned how to use them in my military training. You see, I think I'm much more likely to need them to protect myself from "your side's" extravagantly armed skinhead militias, religious wackofundos and KKK patriots than from any hippy lawyer, Hollywood gay guy or lefty Kollege Perfesser.
