You of course defend the right to own and carry guns and the 2nd Amendment of the U.S. Constitution. Well, put very simply, if somebody wants to take your rights, your property, or your life, it's a hell of a lot harder if you're armed. The Founding Fathers of the United States recognized this and pledged in the Constitution that the government would never interfere, even a little, with the natural right everyone is born with to defend himself with the weapons of his choice. Look carefully at the statement again. Political pacifists are hypocrites who attempt to use government thugs to force everyone else to be pacifists, too.
Libertarians merely pledge never to start the violence.
That's perfectly consistent with a willingness and ability to stop it. In U.S., the right of states to self government gave way long ago to centralized power. They're socialists because neither group would hesitate for an instant to sacrifice the individual for what they conceived of as the good of the collective. Whether we have one big dictatorship, or fifty smaller ones is irrelevant to that process. If I understand what you've asked, here, I don't think that's an issue of central importance.
