“He cites the 14th ( conflating citizen with natural-born citizen ).”
That is because the US Supreme Court says the 14th and the NBC clause are interchangeable:
“The real object of the Fourteenth Amendment of the Constitution, in qualifying the words, “All persons born in the United States” by the addition “and subject to the jurisdiction thereof,” would appear to have been to exclude, by the fewest and fittest words (besides children of members of the Indian tribes, standing in a peculiar relation to the National Government, unknown to the common law), the two classes of cases — children born of alien enemies in hostile occupation and children of diplomatic representatives of a foreign State — both of which, as has already been shown [in their previous discussion on the NBC clause], by the law of England and by our own law from the time of the first settlement of the English colonies in America, had been recognized exceptions to the fundamental rule of citizenship by birth within the country. Calvin’s Case, 7 Rep. 1, 18b; Cockburn on Nationality, 7; Dicey Conflict of Laws, 177; Inglis v. Sailors’ Snug Harbor, 3 Pet. 99, 155; 2 Kent Com. 39, 42.
The principles upon which each of those exceptions rests were long ago distinctly stated by this court. [p683]”

This is an outright falsehood. Nothing in what you quoted says anything at all about the NBC clause being interchangeable with the 14th amendment. It says the opposite. Why do you have so much trouble telling the truth?? In fact it's so dishonest, you have to insert your own words to get the quote to say what you want. What you call the "previous discussion on the NBC clause" was that NBCs were excluded from the birth clause, as was manifest from a unanimous decision which we all know was Minor v. Happersett. The court at this point already confirmed Virginia Minor was HELD to be a citizen by virtue of birth in the country to citizen parents. If the 14th amendment was interchangeable with the NBC clause, then why did Gray not say Minor was a citizen via the 14th amendment??
