Kevin D. Williamson writes that the Democrats have forgotten the difference between citizens and subjects.
The bearing of arms is a sign of citizenship, which is to say, of being a full participant in government who acts through it, as opposed to subjectship, the state of being a passive being who does not act through government but who is acted upon. In that sense, it is like the ability to vote or to be eligible for service in government. Frederick Douglass understood this linkage perfectly, inasmuch as these ideas were much better understood in those more literate days. "A man's rights rest in three boxes," he said. "The ballot box, jury box, and the cartridge box. Let no man be kept from the ballot box because of his color. Let no woman be kept from the ballot box because of her sex." The militias contemplated by the Second Amendment were armed citizen volunteers who could act to use the force of arms to keep the peace in an emergency; they are entitled to act in the peacekeeping role generally reserved for the state because, being the citizens of a republic, they are the state, the very seat of its sovereignty.
Or as Charlton Heston put it: "From my cold, dead hands!"
