Well of course Goths and blacks are offensive! Goths for the way they look and dress, blacks for everything they do and say. I think the main offense for coloreds is their ignorant accent and the way they communicate with the world using half words and slang.
Even when they have riches and can afford to be normal and speak American they still remain ignorant and poorly dressed.
Case in point, here is a colored boy named "Ju" and his garbled mumblings concerning his cash. Who can understand him?
