Not true.
Wong was just a citizen
Well your opinion is that he is just a citizen. SCOTUS said that he was a citizen at birth i.e natural born as in not needing naturalization. There are only two types of citizens. Those who were naturalized and became citizens, and those that were, by the conditions of their birth, recognized as being born a citizen.
Given the fact that this topic deals with law and interpretation of the Constitution, I will go with the SCOTUS rulling for my understanding.
