I'll see your "constitutional originalist" and raise you a "Declarationist", Scalia.

You see, "Declarationists" are a big problem for so-called "Constitutionalists" who go off the rails and start tampering with Natural Rights, because Declarationists have trump.
One should point out to Scalia that the Founding Fathers actually played that trump card, the card that beats tyrannical, despotic (fascist) governments.
Back in those days, states considered themselves exempt from the Federal constitution. Some even had state religions. Using 'local limitations' is an invalid argument. The question is - did the early federal government outlaw certain firearms?
Gov. Henry said it well when he noted that “he smelt a rat tending to monarchy.”
