Here’s a question for you then: can a State maintain it’s Union with the other States yet refuse to acknowledge the Federal Government’s legitimacy [in some action]? If no, then why hasn’t the federal government moved [militarily] on the states that have passed Firearm Freedom Acts? (Such military action would not only be legitimate, from the basis of your argument, but required/needful.)
Can a state legitimately say that the Federal Government has no right to determine it’s standards and/or requirements for education?
Can a state legitimately reject the Supreme Court’s decision in Roe v. Wads? {which stripped states of the right to protect it’s unborn citizens}
Can a state legitimately reject the Supreme Court’s decision in Keelo v. New London? {which stripped people of the right to private property if such larceny carried the stamp of government approval.}
Can a State legitimately reject the requirements imposed by the “obamacare” law?
Can a State legitimately reject the failure of the federal government to defend against invasion by calling its own National Guard to defend against said invasion? (If it cannot, why hasn’t the federal government moved [militarily] on Arizona or New Mexico?)
If you really want answers to these questions look around at your options to get yourself educated. Don’t expect me to give you a free Constitutional Law seminar.
