Gay Rights vs. Antidiscrimination Law

There's an interesting post up at Samizdata on how laws against discrimination by gender and sexual orientation could cause trouble for gay clubs. Paul Coulam writes:

Many gay businesses survive as such only because they can so explicitly discriminate, especially in their advertising. This ridiculous new law will be a very serious threat to the continuation of a 'gay scene' in many towns across the country. It is tricky to foresee all of the unintended consequences of this one. Gay clubs operate varying degrees of explicit discrimination depending on the locale or type of club. The strictest hard core gay cruise clubs generally operate a 'men only' door policy, which does the trick, but this itself may be or may become illegal - who knows what horrors of forced integration are still to come?

However many of the more general gay dance clubs operate what they advertise as a 'gay majority policy' which is usually employed to refuse entry to large parties of girls only. Gay clubs are often the best clubs in a particular town and tend to attract groups of girls who want a night away from predatory straight men. Of course the large numbers of unwary girls in these clubs itself attracts the straight men and before long the club has lost all appeal for gays. In the case of hotels there are lots of hotels in various, often remote, parts of the country that offer gay only accommodation and advertise as such. Will such advertising be illegal? In the short term after this absurd bill is passed clubs, bars and hotels will continue to operate discrimination informally but all it will take is some petulant activist or a council with a bee in its bonnet or some obsessive bureaucrat to stick their ore in to ruin some particular venue or business.
