As I've already said, since 2008 I've been researching this subject.
Vattel’s Law of Nations is referenced in Article I, Section 8, of the U.S. Constitution, so the majority of folks posting on Free Republic are aware of that document's importance on our Constitution as well as that of natural born citizen.
“A natural born citizen is born in a nation of citizen parents”. Nice and simple, it is natural law and doesn't require a legal statute. It is purely logical on its own.
By the way, after the past three intensive years of discussion on this subject, most folks here on Free Republic understand the above information. There are a few who refuse to acknowledge the Law of Nation's definition — keep posting and they will find you, I guarantee it!
Good for you. Earlier you said NBC wasn't a type of citizenship and I showed a SCOTUS case that disagreed. Certainly you should have known this if you've been researching the subject.
