CNN, because journalism, lists all the people who have done "blackface" if, in fact, the meaning of blackface has been expanded to pretending to be black.

The list includes not only actors portraying black people but also -- Robert Downey Jr. in "Tropic Thunder". Downey was not portraying a black man; he was portraying an actor who was portraying a black man. And playing for parody.
