"Most people" believe a lot of things that are wrong. And the Court did not call Ark a natural born citizen. That was not at issue, only if he was a citizen. The only sort of case where "natural born" could be at issue is a Presidential eligibility case. (Or a VP one of course). There has never been such a case heard by the Supreme Court.
But I see you continue to assume your conclusion that "citizen at birth" means "natural born". Even the Surpeme disagrees with that. In some cases "citizen at birht" may be a naturalized citizen. In fact all persons born outside the US, but "citizens" at birth under statute law are "naturalized", for the power of defining a rule of naturalization is the only power Congress has over citizenship.
Oh my! Didn’t you notice that the asshat NS has placed himself in the position of being the rational voiuce, that anyone not in agreement with his obamnoid sycophancy is not rational? Now you’ve done it! You’ll be branded irrational byt the little demigod, NS, and his bottom feeding followers will chide you too.
Congress can't create a natural born citizen. It's beyond the scope of its powers. :-)
