You are trying to brush it aside as a "semantic" issue, and it is not. There is, and always was, a very real and distinct difference between a "Citizen" and a "Subject."
"Subject" is Monarchist, and requires all the inherent foundational principles of Monarchy, up to and including "perpetual allegiance" to the King. Common law only deals with Monarchy principles, not Republican Principles.
Therefore, *OUR* "citizen" is not based on Common law, it is based on natural law principles consistent with Republican government.
Our understanding of "Citizen" comes from Vattel, not British common law regarding "Subjects."
Martin Van Buren, was the first president born in the country under that name change. But History.com is trying very hard to undercut our first 7 presidents as not being NBC, do so as they are leftists who want to put the NBC qualification into question.
