All of these imply that Americans know less about Africa than other continents, which is true (and makes sense, since Africa is the poorest continent and therefore has the least impact on contemporary news, is relatively unpopular as a place to visit, etc). None of it implies that we “think Africa is a country”. > “African American” Asian-American is a widely used term, too.
