Well, she has helped a lot of black writers and directors get deals and their own shows thusly provided entertainment to black folks. She's helped 400 or so black men pursue degrees through her scholarship at Morehouse. Who then in return vowed to pay it forward to other black students. Built schools, donated millions to countless charities over the years. She doesn't seem to like to boast on all she does, which is a good thing. "Do not let your left hand know what your right hand is doing"
But most of that has been mentioned I'm sure. Also considering she don't owe a black, white or green mf a damn thing..I think she's done plenty.
