Then does it follow that since 1872, all of the children born in the US, to foreign citizen parents, have wrongly been given citizenship?
I'm not a lawyer. However the case you cite has apparently been ignored.
Can you explain why it has been ignored for 126 years?
No. It means that the status of children born to foreign citizen parents in the country without leave of the American people is unadjudicated. As Carry_Okie will point out to you, the judicial history centers on those here legally, "with inspection" (Wong Kim Ark, Slaughterhouse cases).
As he pointed out before, the legislators who wrote the 14th Amendment were well aware of the difference, having debated and inserted the phrase "and subject to the jurisdiction thereof". Abiding by one part of the amendment while ignoring the other part of it makes no sense.
By a Supreme Court Justice who was a contemporary of those who drafted the 14th Amendment, no less.

Sovereignty and qualification for citizenship is not in the ineterest of "The International"; i.e., democratic socialism.
