fist, how do you know what the authors of the Constitution and the Bill of Rights did or did not intend when they drafted the Second Amendment? Many believe they viewed forbidding private citizens from owning weapons as the first step to tyranny.

Second, I'm sorry but it is not contradictory to look askance at the continual strengthening of powers of the central government yet at the same time not want local law to be able to supersede the Constitution. I would expect the Supreme Court to overrule any attempt by a city like Chicago or Washington DC to enact a law that inhibits freedom of speech, of the press, of religion, etc. That too is not incompatible with a traditionally conservative view of government. I completely and totally disagree with your characterization of "having your cake and eating it too."
