one voice can make a difference

cnn has an ad right now that portrais a white woman and here child at the park. The child is invited to play with the black girl and her black friends, by the little black girl. The whitle child asks her mother if its ok. The mother responds with "why don't you play with those children. (the camera pans/cuts to a scene of white children playing.) The little girl responds "why?". How do those of us who are criticle of mass media respond to this, it is an obvious distraction tool, but sends a positive message.
