IN 1992, Murphy Brown, a popular TV sitcom character epitomising an intelligent, highly paid, professional woman, decided to bear a child out of wedlock. With righteous indignation, vice president Dan Quayle invoked "family values", the Republican party's watchword in that year's presidential campaign, to attack the show and its star, Candice Bergen. Families, the Republican platform insisted, "must continue to be the foundation of our nation". And, as envisioned by the Bible-thumping Christian right, a family consists of a legally married heterosexual couple with their minor children.
