I don't know. How much can you impede the ability for minorities to vote before it becomes unconstitutional? How much torture can you get away with before it becomes unconstitutionally cruel and unusual? How much can you restrict the abortion rights of women before it runs afoul of the constitution and pre-existing precedent?

It's people asking questions like that, and failing to respect the spirit of the constitution that explains exactly how we've become a nation in which federal power is effectively unrestrained by the constitution.

Endorsing gun control means being an enemy to the bill of rights. Wiggling past scrutiny by playing legislative "I'm not touching you" games as you're doing weakens the whole of protections to the citizenry. Whatever semantic games you like playing against the second amendment sets precedent for those same games to be played by the other side for speech, privacy, abortion and marriage rights. It is the failure of the left to respect some rights, paired with the failure of the right to respect the others that has gotten us where we are.

Just because the government doesn't like a right doesn't mean they get to ignore it. Because people like you let them selectively ignore the rights you don't like is what gives them the power to ignore the rights you do. If you want to be constitutional (and you should), you can ban bullets by repealing the second amendment, or amending the constitution to state that bullets aren't protected by it.

I think you missed my statements several times that I am not a supporter of gun control, but asking why those that are in favour of gun control don't go after ammunition rather than guns.

As for the second amendment it has basically been totally gutted long ago since people have no access to true arms.
