Somewhat off-topic:

In the 19th century and earlier, people who are now called African American used to use the referent "African" for themselves. Two examples that are still in use today are the religious affiliations AME [African Methodist Episcopal] and AMEZ [African Methodist Epistopal Zion.

For various reasons, we [African Americans] used the group & individual referents "Negro", "Colored", "Afro-American", "Black", and others. In the 1970s, "African American" became the formal referent for Americans of non-White African descent {although that "Non-White" part isn't entirely correct since many African Americans have some White ancestry}. "Black" is still used as an informal referent for this racial group {though some Black Americans have lighter skin color than some persons who are designated White}. "African American is the formal referent. Given that for so many years African Americans were socialized by mainstream American culture to be ashamed of their African ancestry, in my opinion, it is good that many of us not only acknowlege but also celebrate that ancestry.

That said, I agree that Europeans and Asians living in Africa are also Africans and that when they come to the USA {not to mention Canada and South America} they could legitimately be called "African Americans}. I also know that there are many African cultures, and at many sub-groups of African Americans who have been in the USA for generations. And I know that there are other people throughout the world who are called Black.

Confusing, yes. But it bes that way sometime.
