You should also think about what your response would be if the government repealed (according to all of the legalities set forth in the Constitution) the 1st Amendment (that's right, the 1st) - do you think that such an act would enable it to outlaw the possession of Bibles, attendance at a house of worship, etc.? If not (and I certainly hope not), then you should consider the effect of the laws that outlaw or restrict the possession of certain firearms, much less the repeal of the 2nd Amendment that the gun-grabbers so desparately hope for at some point in the future. These existing laws are as repugnant to our way of life as a law that would ban Bibles. Registration of guns is as repugnant as registration of Bibles.
Try to think outside of the box. Don't be too caught up in thinking that if there's a law that says something, that it is somehow OK. The Nazis were masters at legally implementing the most repugnant and odious laws in the history of mankind, and their judges obediently said that it was all legal. No one, however, bothered to stand up and say that the whole idea of government legislating about certain things was impermissable (maybe, perhaps, because guns had already been confiscated from all opponents of the Nazis - how's that for a tie-in?).
Semper Fi! And never forget... You're not alone...
