The point was that you claimed, falsely, that a previous Court had said the "exact opposite" of Wong Kim Ark.
They didn't. There was no such ruling in regard to citizenship as what you claimed. Ever. Not even in Scott v. Sandford.
Scott v. Sandford never said the children born here of aliens weren't citizens, or weren't natural born citizens, or had to have two citizen parents in order to be natural born citizens or eligible to the Presidency.
Scott v. Sandford said black people were regarded by the Founders as an inferior class of beings, not included in the "people of the United States," and that therefore they were not and could never become US citizens.
It was a bad ruling from the very beginning, as the claim violates the very first sentence on which our entire Republic was founded: "We hold these truths to be self-evident: That all men are created equal, that they are endowed by their Creator with certain inalienable rights; that among these are Life, Liberty, and the pursuit of Happiness."
And that ruling was recognized as garbage pretty much from the very beginning. Lincoln's Attorney General Edward Bates wrote an Opinion in which he basically said that their comments on black people not being able to be citizens were garbage dicta, and the Lincoln administration was simply going to ignore them.
