You obviously didn't read up on the meaning of "AND subject to the jurisdiction there of". The physical location on a va**na does not confer legal citizenship upon the child being born from it and it never has. "Birthright citizenship" as it's called was never passed into law or ratified into the Constitution. It was a policy put in place by INS in the 1960s, which makes it a policy of the executive branch. Thus repealable by executive order. It's not a passed law. Not a ratified amendment. Therefore not a constitutional right.
