If you let the media shape your beliefs about an entire race of people, yes, you're a DUNCE. Just like you're a dunce for thinking white people are born racist.
Black people are only 13% of the country, there are a LOT of white people who only experience Black people through various forms of media and stereotype blacks based on how they've seen Blacks portrayed in the media, are white people dunces because many of them think we're supposed to fit into a false stereotype?
