Fortunately for all of us, the Founding Fathers did not leave behind an explicit set of instructions on how to exactly interpret the contents of the document hundreds of years in the future, so we all get to have fun arguing like a bunch of religious fanatics as to which belief is the Holy Truth. How about we just all admit that we interpret the Constitution how our narrow-minded views of the world dictate and leave it at that?
James Madison didn't want a Bill of Rights because he was worried that would cause dumbass "strict constructionists" would decide that other rights weren't protected by the Constitution.
