Thank you but I'm already very familiar with Article II.
As I pointed out to you, a person who is naturalized is a person who becomes a citizen "subsequent" to birth and not "at" birth.
Read the law.
A person is "naturalized" according to any requirement congress wants. Congress put in the stipulation that it be "at birth" but they could have stipulated six months after, had they wished. They DID stipulate an AGE requirement for the mother. If the mother is too young, the child doesn't get any citizenship. Does that sound like "natural born" to you?
The point is, you are confusing citizenship by an act of law with being a "natural citizenship", merely because it happens at birth.
