Black people in America are just as ignorant about Africa as white Americans are. This doesn't sit well with Africans, because it's one thing for white people to be ignorant about Africa, but it's another thing for BLACK people to hate Africans. Especially the ones who are only 1st generation African Americans. don't think most people outside of America are ignorant of American history and culture. Immigrants sort of have to know it if they want to be citizens and I don't think that really diminishes the dissonance they have for Americans. In this case Africans for black Americans.
