I agree for the most part. Pandering is never a good thing but a positive image has to come from somewhere I guess. Kanye and Suge Knight are not very good role models imho. Of course neither is Bieber boy.
I see the same thing with Latino-focused advertising but I think that is changing. Until now it has been a separate society in a way, sitting right alongside mainstream American society. Now there is more integration as new generations are born. Hopefully for US it is a good thing.
