“A few years ago, a Nigerian-born playwright came to a talk that I gave at the British Library in London. She was intrigued by the lecture, the idea that 6 million African-Americans had had to seek political asylum within the borders of their own country during the Great Migration, a history that she had not known of. She talked with me afterward and said something that I have never forgotten, that startled me in its simplicity. “You know that there are no black people in Africa,” she said.”
