American citizens, not natural born.
What about the Anchor babies; those born of a foreign national mother on American soil?
American citizens, not natural born.
By your own definition, HMV, Anchor Babies are not even citizens because neither parent is a citizen. But it is a fact that anchor babies are indeed citizens, so your definitions are flawed.
Not to mention that the Constitution only lists 2 classes of citizen, natural born and naturalized. So unless you can provide some other legal source for three classifications, I'll take the Constitution over your opinion any day.
