Regarding the Second Amendment and the right to self-protection: Going back to the dawn of civilization, before man-made laws, the right of self-protection was never questioned.
There was no debate over how many rocks, clubs or sharp sticks were necessary to defend one’s self or family from predatory people or animals. The right, no, the obligation to self-protection has changed only in the implements used in modern times. Now gun control advocates argue over the number of guns, bullets or clips necessary for the purpose. Be it sharp sticks, clubs, guns, ammo or clips, the right to self-defense predates the Second Amendment by millions of years.
Natural law still trumps man-made law.
