Here is an interesting piece from Jefferson writing about the commonwealth (Virginia, I assume) in 1779:
and all infants wheresoever born, whose father, if living, or otherwise, whose mother was, a citizen at the time of their birth, or who migrate hither, their father, if living, or otherwise their mother becoming a citizen, or who migrate hither without father or mother, shall be deemed citizens of this commonwealth,
Interesting look at Jefferson's thinking on the subject about a decade before the Constitution.
Citizen yes, NBC?
There is a reason Citizen and NBC are differentiated on the Constitution, I wish it was more clear.
I wish the 2nd Amendment only just stated "the right of the people to bear arms shall not be infringed" too.
What the Founders thought was a clear meaning of words, semantics, would not change was a mistake.
Other than that, I trust in their wisdom explicitly!
One more remark, following your blockquote. Citizenship tended to follow that of the father, at the time the Constitution was drafted.
