Well, this is one of the craziest stories I've ever read.
The woman in that clip is Rachel Dolezal. She is the leader of her local chapter of the NAACP in Spokane, Washington, an adjunct professor of Africana studies at Eastern Washington University and sits as the chair of the city's police oversight commission. She is also white.
Of course, a white woman could do and be any of the things listed above. There have been white chapter leaders of the NAACP, white African professors and white civil rights activists. But Rachel Dolezal has been doing them as a black woman.
