I've been told that FOB is offensive and is rarely used in a positive, or even neutral, manner. I mean it hasn't become taboo like nigger has but I've been told its not a polite thing to call someone. But my larger point is African American "works". Its not offensive, speaks to a unique identity the same way Italian/Jewish/German American does, and for the most post is accepted by the black American community. Also the genetic pool won't equalize anytime soon. Admixture leading to a near homogenous population of humans outside of small sparsely populated areas is millenia away.
