Black and white in Asia are tanned or not tanned skin, just to clarify. Although it is a bit of racial discrimination, it is more like a social one... If you are tanned, it means that you had to work in the fields and who does stuff like that? The poor insignificant "lowlifes"... White skin is a symbol of prestige, higher social class... I am not saying that I am ok with that, far from that, it is just that I think it is good to teach people the background...
