SAN FRANCISCO (AP) — San Francisco drag queens are sparring with Facebook over its policy requiring people to use their real names, rather than drag names such as Pollo Del Mar and Heklina. But the world’s biggest social network is not budging from its rules.

In recent weeks, Facebook has been deleting the profiles of self-described drag queens and other performers who use stage names because they did not comply with the social networking site’s requirement that users go by their “real names” on the site.
