Registries and the defense against one-
If the Government were to institute a background check that feeds into and is checked against a federally manged registry for a relatively controversial right- say guns, or abortion (as the two that leap off the drawing board at me) what arguments would be used to challenge such a thing? Other than the fact that many but not all in favor of one are not in favor of the other- and noone wants the slippery slope of one to drag the other down with it.
Would this be government intimidation? Invasion of privacy?
