For all practical purposes, there's almost no such thing as an African-American that isn't part white.
Interestingly, it's estimated that about 25% of American Southerners who consider themselves white are partially of African descent.
When the subject of "Reparations" comes up I always thought that the people who want reparations are probably the grandchildren of both slave and master. My caucasian ancestors came here long after slavery was over.
