>>> So by the definition given then they are citizens by rule of law and not natural-born citizens.
Those who are MADE citizens by law are naturalized.
Those who are made citizens because their parents are citizens are natural born.
The founding fathers and every other American at the signing of the declaration of independence were naturalized. This is why they had to make an exception in the constitution for the first generation of Americans to be eligible to run for president.
The first generation of black Americans at the implementation of the 14th amendment were MADE citizens by law, making them naturalized. Any children which were born by them AFTER that would be natural born. (inheriting their citizenship from their parents)
Inheritance of your citizenship is NOT an act of congress. This is from “Law of Nations” and was well understood by the founding fathers. To be born to citizen parents of ANY country is to be natural born of that country by birthright not law.
Any law establishing citizenship by other means than inheritance is naturalization.
Black Americans born to citizen parents are natural born, just as any other American of any color is natural born if their parents are citizens.
Ted Cruz is a citizen because his mother was a citizen. So Ted Cruz is a natural-born citizen?
