I also would like to point out that such a suggestion was not even a consideration until very recently in American history. There was a time when the question would have been "What do mean you don't own a gun?!" (not that everyone carried but almost everyone had a gun in the house). The founders CLEARLY never intended any level of training our they would have either written it into the Constitution OR required it by later law and neither has been the case.
Still happily answering to the call-sign Peetza.
The problem, as you so eloquently put it, is choice.
You do not HAVE a soul. You ARE a soul. You HAVE a body.
He is no fool who gives what he can not keep to gain what he can not lose.
