To name a few lol, but in the good ol' U of K has hardly had any all i can think of on the top of my head is the Desmonds. Why is it that America can recognise that they have a large amount of ethnic minorities, when Britain the country i live in claims to be multicultural, but cannot recognise its multicultralness on the television level. Why can't black people cross into mainstream. Why is it that we have to get excited over story lines which portray us in negative lights such as drug dealers and knife and gun hooligans...just because there is a black person on the TV?

Mixed Emotions
