As with anything to do with upper class oppression of the lower in American history, the guilt and blame has been shifted from upper class to white and all of the hurt shifted from the white slave and lain on the shoulders of the suffering blacks. However, as shown below, the term boy entered the English language before English-speaking people held any black slaves and was coined to specifically denote a servant boy, where a free child or youth of the male sex might be referred to as a kid, laddie or lad. Blacks are right to resent this term, and whites are wrong for willfully forgetting that it was first used to describe English, male slave children. To be labeled a boy was to be called a dog.

-offensive (often used as a form of address) a black male servant or worker.
