I have come to the fixed opinion, that the invocation of the above is almost invariably disingenuous by whomever utters it, and almost always attended by ulterior motives. In Torie's perfect world, there would be no states rights, just prudential agency authority given to the states for prudential reasons. We are one nation now. The states rights notion has typically been attended by mischief, and still is, but now is embarrassingly archaic, sort of like the appendix.
Then you don't believe in states. You must be an anarchist, congrads. In Libertarianben's perfect world, people would actually read the constitution and follow it.
