More like saying “These are a member of this set” instead of “This set consist solely of these”.
“Children born of two citizen parents are Natural Born Citizens” is a different statement than “Natural Born Citizens are children born of two citizen parents”.
That part is covered when the court says “as distinguished from aliens or foreigners” and “As to this class there have been doubts, but never as to the first.” In this context, it becomes an exclusive definition, used to characterized only ONE set of citizenship criteria: all children born in the country of parents who were its citizens.
Nope, the case says that there is a class of citizen, the natural born citizen, that nobody doubts or contests their citizenship. These natural born citizens are persons born within the jurisdiction to 2 citizen parents. There are other people that have debatable or sometimes argued citizenship, but they don’t matter in minor v heppersett, because in this case the woman has NBC status.
No way around it.
You are either deliberately misleading in your analysis and reading of the case, or lacking the mental capacity to comment on it objectively.
