You read my comment up above citing minor which says "The Constitution does not, in words, say who shall be natural-born citizens." and you still want to post that the 14th defines "natural citizen"?
That sir, is cognitive dissonance.
The Constitution did NOT spell out the meaning of NBC because the meaning was already understood. It was a well known legal term, long used. And that long accepted meaning included those born of alien parents.
That was the Supreme Court’s point - the wording used in the 14th was a restatement, 100 years later, of what everyone understood the term to mean when the Constitution was written in 1787.
