I think your nuts.
You think that the Constitution just automatically changes meaning over time to agree with what you think is best? Why write it down? We can just ask you whenever we need to know how new situations should be handled. Or, if not you, we can ask the judiciary. Or we can ask whichever party happens to control Congress at the time.
The Founders gave us a means to change the Constitution. It's been used several times to make dramatic changes to what was thought by our Founders to be the best way to constrain what is supposed to be a limited government.
If an amendment to the Constitution specified that everybody who is at least four-years-old should have the right to vote, would that be a good idea? Would it be Constitutional? Would you expect Congress just to legislate in violation of that amendment? Would you expect the courts to permit violation of that amendment?
