IS there anything more boring than the debate about political .correctness? As if the trinity of race, class, and gender hadn’t become tedious enough, now denouncing political correctness has become encrusted with its own clichés. At the moment, a cable-TV show, a book, and a Broadway production carry the title Politically Incorrect and seem to applaud themselves for their supposed courage. The whole thing hit the point of absurdity when, on a late-night talk show, the actress Whoopi Goldberg announced that she detested political correctness. It was all one could do not to hurl something at the television and shout: “Ms. Goldberg, you are political correctness.”
