So, if I have this correct, Adam, and others are in here arguing that this so called 'loophole', which BTW, is not even nationwide, nearly half the states have restricting law on the books concerning shows, or private sales, but that they want a law on the Federal level restricting sales by private individuals. However, their problem that they can't get around here is that pesky Constitution, and their never ending seeming ignorance of who holds, or derives power as the framers set up our system of government.
Which is why earlier I made the statement of how communities could govern these matters for themselves, and those that don't agree to give up their constitutional rights to the overlord of liberal/progressive government can move. But see, this is part of the incrementalism that I spoke of also. The ultimate goal of any progressive, is to drain the rights of an individual as we believe them to be granted, of divine providence, and shift that to rights granted by man, and or government.
Now, when that happens, what man giveth, man taketh away.
