If there comes a day when "they" come get your guns, it will be to the extent that one more or less won't matter.
Anyone who can be identified as a "gun nut," say, anyone with more than a hundred posts here, will be subject to special methods. Once they have a gun to the head of my wife or child I don't think I'd be holding out the SKS I got through the paper.
That's assuming they don't just kill me out of hand. The idea that totalitarianism on the scale of overturning the Constitution to such a massive degree will be satisfied with just what's on paper or will have scruples about "making sure" of any extras is, to my mind anyway, the kind of middle ground thinking contrived to allow for the "last stand" fantasies we all hold so dear in the national mythos.
