Can anyone explain to me why we don't use brown? I've always grown up knowing we cant say it (I'm 18 now) but where did that come from, I know its a derogatory saying but its clear that that woman isn't actually black although most would say shes black and the other woman is white. I would never use brown but when did it become a derogatory saying and why? I'm not being dumb either, I would normally say mixed raced.
