The justices "knew" who belonged and who didn't, and simply reached for whatever rationale would allow them to get the result they wanted.

One year, "science" trumped a common sense argument.

The next, "common sense" trumped claims of science.

Pretty damn Caucasian, actually.

The very next year, SCOTUS heard US v Thind, in which a South Asian Sikh insisted he was technically part of the Caucasian race based on language and anthropology etc.

The court said, ha ha, no, by "Caucasian" we mean white.

In the 1922 case of US v Ozawa, a Japanese immigrant to the US essentially pointed to the color of his skin and said, look, I'm white, I should be eligible for naturalization.

But the court, embracing the new "science" of race, said, no, by white we mean "Caucasian"

Noooo!!
