That’s a straw man argument. No one has made NBC mean “citizen.” No one is arguing that and no one is suggesting that (except in straw man arguments like yours).
What NBC means is “born a citizen” (in contrast to “naturalized citizen”) and you can look that up in any good textbook on the Constitution. Even the birther-beloved Minor v. Happersett decision said that there were only two kinds of citizen, born and naturalized.
There are three kinds of citizen.
Natural born, native, and naturalized.
The culture war on America has been so successful few are left with the cultural knowledge to refute your false claims.
Whoever, then, was one of the people of either of these States when the Constitution of the United States was adopted, became ipso facto a citizen -- a member of the nation created by its adoption.
Waite said citizens could be added by birth or naturalization, but he NEVER said there were only two types of citizens. Under the addition of citizens by birth, he identified at least TWO different classes, natural-born and those born in the country without reference to the citizenship of the parents. NBC does NOT mean "born a citizen." There's NOTHING in the Supreme Court precedent that defines it this way. Instead the SCOTUS defined NBC exclusively as "all children born in the country to parents who were its citizens." What would be the point of saying anything about parents being citizens if NOT for how it was used to define NBC??
