True. Coloured people, West Indians, darkies, blacks, and many more (some of which I wouldn't dare to mention on here) have all come and gone. If all of these words are 'unacceptable', it must be something else...
Just a whiff of "I'm not a racist but" floating around here together with a healthy dose of ignorance. Both tend to go together.
To help you out, MOBO stands for music of black origin. It apparently applies to some sort of urban music which I'm not keen on and not proper blues which I am.
I presume you think it is awards for black artists? It isn't. Joss Stone has won for instance.
