[Non-Sequitur]

Not many terms are defined in the Constitution, Treason being an exception. But that doesn't meant they didn't have known definitions at the time. Whatever those were, they still are.

If not defined in the Constitution, like treason is, then they are defined by law. And the current law does not define natural-born citizen the way you do.

So, again you are saying that congress can simply amend the constitution as easily as changing any law?

I guess you'd be OK with Congress passing a law making writing on an internet forum neither speach nor press, and thus subject to anything Congress wishes to do with it.

Laws cannot define any Constitutional term, for that would allow them to change the Constitution.

If you mean "case law", there is no case law directly on the subject, for the only time the distinction matters is for eligibility to the office of President.
