I found it odd that his fathers race was listed as AFRICAN? His mother’s race is listed as CAUCASIAN. Is African something a modern person chose rather than the currently unPC negro?
No, because he is not Negro-African.
He is 50% Caucasian, 43.75% Arab, and only 6.25% Negro-African. He doesn't have the lawful 12.5% Negro-African to legally claim to be African-American. Barak Hussein Obama is ARAB-AMERICAN.
The term "African race" as well as the term "Hebrew race" were regularly used in legal documents in the United States at the time of Obama's birth.
In FR you are expected to know such things.
