Sorry, but the only person who has "blinded" himself is you. Read the decision. Minor's claim of citizenship is a central part of the case:
The argument is, that as a woman, born or naturalized in the United States and subject to the jurisdiction thereof, is a citizen of the United States and of the State in which she resides, she has the right of suffrage as one of the privileges and immunities of her citizenship, which the State cannot by its laws or constitution abridge.
Her citizenship was part of the question and the court (part of which you quoted) rejected her argument on the basis of the 14th amendment because she was, by the court's definition, a natural born citizen.
If she had an alien parent, THEN they would have needed to determine if NBC applied to those born with alien parents - but she did not have an alien parent.
Sorry, but the court said if she was not born in the country to citizen parents, then doubt would need to be resolved about her simply being a citizen. If she was a natural born citizen, there would be no doubt. Thus, anyone who does not meet the definition of born in the country to citizen parents is not a natural born citizen. They MIGHT be a citizen, such as through the 14th amendment, but they are not a natural born citizen.
“Sorry, but the court said if she was not born in the country to citizen parents, then doubt would need to be resolved about her simply being a citizen.”
Given that the 14th had passed, this statement is simply false.
The court found there was no doubt about her having been a citizen by birth, and it was admitted in the case - so citizenship by birth was not the issue.
I’ve quoted the court case. Your quote confirms what I wrote:
“The argument is, that as a woman, born or naturalized in the United States and subject to the jurisdiction thereof, is a citizen of the United States and of the State in which she resides, she has the right of suffrage as one of the privileges and immunities of her citizenship, which the State cannot by its laws or constitution abridge.”
In this case, it didn’t matter if she was a citizen by birth or naturalized. Does citizenship confer the right to vote? That is what they were asked, and that is what the decision is about.
