If a kid is entitled to citizenship by birth, he's natural born. Period.
OMG! Your own words give you away.
@entitlement
An individual's right to receive a value or benefit provided by law.
By positive law, not natural law! Positive law is legislation! Congress can only pass laws on naturalization.
@positive law
Those laws that have been duly enacted by a properly instituted and popularly recognized branch of government.
Entitlement to citizenship is not the same thing as entitlement to welfare or food stamps or social security or medicare (but I repeat myself).
