Because
A) I don’t want to be sidetracked.
B) I want to know if there are ANY other sections in the Code where it defines what kind of citizen a person is, depending on his parents citizenship and his birth location .
If the section we are looking at is the only place its defined, then the question is settled.
Thus those who resort to such statutory law only further emphasis the point that the person they're supporting with such usage isn't a natural born citizen and they only seek to confuse the issue.
