I've seen Maya Angelou transform people about their race. I saw the change in Tupac after working on a film with her. I remember the total change in Dave Chappelle after spending time with Maya. She herself having once been a prostitute who then read her poetry at the White House at the ceremony to welcome our first African American president.
These are people, and images, that support African American achievement. Not images of the homeless, nor dancing around like a whore in a brothel where she would have been called a "high yellow whore" if this had been even 50 years ago. There was a time when African American music videos weren't even allowed on MTV - and now she's performing at the Superbowl.
Why wouldn't she be when she's perpetuating the images that the Aryans who own major media want perpetuated? She's doing their job for them.
