You even see it in the cartoons, that should be teaching children to be more tolerant of others and to be respectful, have the bad guy or the antagonist in the story to be a person of colour or differnt ethnicity. That is wrong to teach to kids because they believe that is what it is like in the real world. And it clearly is not. And What are the coloured children watching the same shows supposed to think? They are made out to be terrorists or evil maniacs in these cartoons, so is it telling them to be like that when they get older. They may think that is all they do and all they are good for, and to have a child think those things about himslef are terrible.
In order for television to be a more diverse home for all races, they must first recognize all races on the shows they give to the public. By putting other race characters in the shows it tells those people that they can be more then a sterotype. Diversity matters in television so children do not grow up thinking these things about there fellow man, and televison should portray every race the same way.
