Technically speaking their are only four (sometimes 5) race classifications. Arabs and a lot of Africans actually fall into the Caucasian race, but this is not the point. The validity of Obama's nationality has nothing to do with race, except for the fact Obama and his supporters keep making that claim. Nationality IS a strictly defined qualification for the office of presidency as laid out by the letter of the law in the Constitution. That in my opinion should have been a small issue cleared up early on, yet it wasn't and should have lead to a Constitutional crisis, but alas the Constitution doesn't seem to hold weight anymore. I find it amusing those that claim to want to be strict Constitutionlist are some of the same ones who (at least on this forum) claim any question of Obama's nationality is race based, conspiricy theory, propaganda, from the uninformed.
