I listened to the LBC phone-in for quite a long time in bed. The presenter, himself half-white-half-black seemed eminently sensible, but then an elderly white lady phoned in to tell how her black husband of over 50 years had once told her about black folk calling each other n-----s. She spoke the word, and the presenter was on her in an instant, not in a nasty way, and she was cut off. He then explained that it was ok to say n-word but not n----r. It is a bit daft, everybody is walking around now saying n-word, p-word, i-word, j-word, when everybody knows full the underlying actuality. Incidentally, the expression "white trash" was free to air on the programme. Next stop, thought control.
