"The matter of who's "more" black has a certain personal resonance. Like many foreign blacks, I'm often treated by my black peers as a usurper. Furthermore, my children have the same pedigree as Barack Obama: Kenyan father and American mother. After three decades in America, I still anguish about the sad state of the relationship between American and African blacks. Each group, safe within its own prejudices and preconceptions, rejects the other."
