NO, NO, NO. What is in 'doubt' is if they are CITIZENS, not natural born Citizens. The purpose of this passage is to acknowledge the issues of the infamous 14th Amendment - PERIOD.
The reason is it not necessary to solve is because Minor's citizenship was NOT based on the 14th Amendment. She was a citizen without the 14th Amendment. So the statement 'it is not necessary to solve these doubts.' means the judgment is simply not addressing the overly broad interpretation of the 14th Amendment. Why - because Minor WAS, BY DEFINITION IN THE RULING, a natural born Citizen.
What the ruling is saying is - "if you got your citizenship from the 14th Amendment you are specifically NOT a native or natural born Citizen." Native or natural born Citizen is specifically defined and specifically separated out from "anchor babies". THAT is what this passage is about. And that is why it specifically defines - legally - natural born Citizen.
Since Obama definitely belongs the class where 'there are doubts' by SCOTUS DEFINITION, he does not belong the class where there are no doubts - the class being that of native or natural born Citizen. And yes, the definition says 'parents' (PLURAL). Mommy alone does not get it done - BY SCOTUS DEFINITION.
Well put!
