Race as biology is fiction, racism as a social problem is real: Anthropological and historical perspectives on the social construction of race.
Because "black" has and still serves as a marker for categorization in the skin color based "race" system. And as we know(hopefully) "race" is not an observable phenomenon based in any science, whether in the study of culture or genetics. Thus this "color"(or lack there of) not a sufficient title for any ethnic group of people as it does not represent our heritage, ancestry, or history. I primarily use African-American, but would also be okay with "Afro-American", or the portmanteau "Afr'am" which might actually be the best option because it doesn't give the impression that our title is just two words of continents put together, but ONE word which has it's linguistic root words in two continents that denote our ancestral continent and the continent of our ethnogenesis.
