I completely agree - my point is that those who argue against all sorts of elective actions by the feds - that is, stuff not mandated nor expressly forbidden by the USC - on Constitutional grounds are all wet.
It is your position, then, that anything that is not expressly forbidden, is allowed? Why, then, was there any attempt to enumerate the powers of the government? Without the Second Amendment, would it be permissible for the government to disarm the people?
