I guess I can see where she's coming from, but still..
Her father definitely didn't want Black Americans using it and promoting it through a multi billion dollar hip hop industry. Neither would MLK Jr for that matter, but I that's too touchy of topic.
It's become a part of "hip" American culture more or less and she's probably ashamed and or crazy, after all her father fought for, we got people of all races in America throwing around a word whites gave black slaves hundreds of years ago.
