They don't bring on white writers when they include white characters in their stories (speaking of Final Fantasy), why would they think to do it for a black character?
About the hip hoppy comment, that's just ignorance. Think about how ignorant the average American is about cultures in other countries, these other countries are just as ignorant about us. And it doesn't help that America only presents Black people in certain ways, the majority of the time you're reading about a black person in American news it's hip-hop or sports related, (crime as well) and that;'s exactly how people in other countries see us. It''s the system.
