"They tell us that we are weak - unable to cope with so formidable an adversary. But when shall we be stronger? Will it be when we are totally disarmed, and when a British guard shall be stationed in every house? Three million people, armed in the holy cause of liberty, are invincible by any force which our enemy can send against us." - Patrick Henry

"The right of self-defense is the first law of nature; in most governments it has been the study of rulers to confine this right within the narrowest possible limits. ... and [when] the right of the people to keep and bear arms is, under any color or pretext whatsoever, prohibited, liberty, if not already annihilated, is on the brink of destruction." - St. George Tucker
