If you understood the historic origins and scope of the treaty power in the Constitution, you would be.
I looked at it and it looked like a fairly straightforward statement of principles against a broad-front attack on our rights by the international Lords-Ordainer wannabe's.
Sad experience has taught me otherwise.
I think I have your drift, and yes, Fedgov has been coloring outside the lines since Webster floated the first iteration of the "Mystical Union" crapola and John Quincy Adams floated the idea of pushing the South into secession, shouting "insurrection", and then using the succeeding military confrontation to "reorganize" the Southern States politically. Which, btw, is the best-kept secret in Civil War history; I didn't know anything about that, until people began trading comments on a passage in the new biography of Adams. Since the Civil War, Fedgov has "gone ape" and needs to be trimmed off and our constitutional damage redressed.
But the NRA isn't the problem here -- it's people like the Pew Trusts, the other assorted Prog-driven NGO's, and the international movable-feast class.
