The black people
The black people that live outside of Africans can still be considered as Africans. Whether the Africans migrated to outside Africa voluntarily or involuntarily, they still hold onto the same cultural identity on the basis of their social conditions and their origin. Hence, regardless of the part of the world that the people with the African origin are found, they portray various similarities in cuisine, speech patterns, art, religion, community organization and their world view that generally pay homage to the legacy of their African experience. Cultural identity is essential for every individual and once you associate with it you become part of it. The same happens to the Africans out of Africa, even though they may term themselves as diaspora or try to associate with the host country, they still identify with the African identity making them Africans still. Further, a majority of them go ahead and form black societies and these allow them to retain their Africanism, hence demonstrating strong linkage to the African origin.
However, the argument that the people are no longer in Africa and some never have the hope of ever going back to Africa makes them argue that they are no longer Africans and hence they identify with their host country.
