In Hawaii (where Whites were a minority) it might have been different, more like things are (I hope) now.
I really feel the need to repost this. (I am sorry I am replying to your specific post. It was the closest post I found that was on topic.)
I have an original Hawaiian BC from 1968. (I know that Obama’s document is not original)
The “race” of the baby or parents was not asked or documented on the Birth Certificate. My Father tells me he was not asked either, while giving the info for the BC.
My sister was born in Hawaii 4 years earlier, and she tells me it is not on her BC either.
So again I ask, why would this info be on his replacement?
My answer is this is not a real document and the info was added to this to show that he always was considered African American. There probably is a document somewhere, which lists him as some other race.
I know it doesn’t matter, but it obviously matters to someone responsible for producing this document.
