It’s the old Helmut Sonnenfeldt “as...as” construction.
A Hippo is as much of mammal as a man.
I really don’t think your argument about Justice Roberts makes sense even for a troll. It is in fact absurd.
Okay, but until there is legislation or a court case that specifically prohibits a person who was born in the U.S to a non-citizen from becoming president, there does not seem to be any prohibition against it.
And as long as we have a 14th Amendment and an Equal Protection Clause, there is not going to be a prohibition against such a person being president.
And, it would appear that you have living proof in the White House at this very moment and the SCOTUS obviously has no interest in the matter.
