I´ve heard Paul Robeson (my idol) who was really black, using the word "darkeys" without hesitation. I'd never suspected that the word could be offending to anybody. As a white who loves gospel and negro spirituals, singing for a white audience who loves them too, I'm discovering my ignorance on some subtleties. Please advise on what could be troublesome.
