Saletan spots another sign:
San Francisco is famous for tolerating nudity. Men in chaps, jockstraps, and sometimes less stroll around at annual festivals such as the Gay Pride Parade, the Folsom Street Fair, and the Bay-to-Breakers street run. But what used to be a confined, occasional indulgence has become a chronic nuisance. … [But now] residents of San Francisco’s Castro district, possibly the most gay-friendly place on Earth, persuaded the city’s board of supervisors to pass an ordinance restricting public nudity. The rise of same-sex households isn’t making society queer. It’s making gay people bourgeois.
My thoughts on the subject from 2005 here.
