You ask "Where is this well regulated? militia" ... Well Ma'am it is the responsible citizen that is well armed and reports to defend the Constitution and freedom should that freedom ever be threatened by tyranny. A first step in the direction of tyranny is to cripple and then destroy that Right. The Second Amendment is much more than a right to own a gun, it is every freedom loving citizen's duty and responsibility.
Arm yourself, take a firearms safety course and your fear of my Second Amendment Right will go away.
