Is an Egyptian who moves to the US an African American? What about someone of Dutch heritage whose ancestors lived in Africa for 350 years, and then moves to the US? Can they be called African American? What if they also have Zulu ancestry? Does it depend on what they look like, or does it depend on what percentage is Zulu? What about someone whose ancestors lived in Jamaica for hundreds of years, ancestry unknown, but dark skinned. If they move to the US and "look" African, can they be considered African American? Or can you only be called African American if your ancestors include those subject to slavery in the US?
