SCOTUS ruled that way even knowing that both of WKA’s parents were non-citizens. The dissent in WKA even recognizes that the majority opinion in WKA makes WKA a nbc and eligible to be president. All courts since WKA have taken the same legal position, that if a person is born in the US sovereign territory, you are a nbc, no matter the citizenship of the parents. Again, since WKA, you cannot show one case that uses the bogus Vattel theory to define nbc.
And that alone should tell you how absolutely stupid was the decision, yet here you are, telling us all that it makes perfect sense.
The 14th amendment itself is of dubious legality. Far from being a consensus of free states, it was passed with Federal Armies occupying Southern States with intimidation and threats of dire consequences to those states which refused. Passing it was in fact, a requirement for them to be relieved of the occupation troops. The congress did in fact, have a gun pointed at their head when they made them do it.
The 14th amendment, has consequently been the source of much federal mischief. It has allowed the courts to force their own personal ideology upon the states, and justified many excesses of federal power. It is the cause of Prayer being banned in schools, Intolerance of religion on public property, abortion, and many other things it was never intended to do, but was twisted into doing by the very courts you wish to worship as infallible.
No doubt you would have felt the same way regarding the "Volksgerichtshof." They would have ruled that Kristalnacht was perfectly in accordance with German law. All hail the idiot courts!
