Re. your comment: “A woman’s rights are not violated if her son is not ‘natural born’. If you think that argument is gimmicky and unfair, I agree. But we must not expect the other side to be fair.”
I do not consider such an argument to be either gimmicky or unfair. This goes to the heart of the meaning of the phrase ‘natural born citizen’. My own view is that there never has been unanimity on the full meaning of this term. Some thought it included only Class A and no others. Some thought it included both Class A and Class B, but not C. Others thought it included Class A and Class C, but not Class B.
Where:
Class A represents children born in the territory of the US; both or one citizen parent
Class B represents children born in the territory of the US; neither parent a citizen
Class C represents children born outside the territory of the US; both or one citizen parent
I could add more classes and/or subclasses - it doesn’t stop here.
I think for the understanding of all and in the interest of clarity this phrase could be altered by Amendment to read “Citizen by birth”.
Where are the ‘class A, B, and C’ codified?
