Gays in San Francisco’s famed Castro district are upset because of an element that is moving in: heterosexuals.

[S]ome gay and lesbian residents of the Castro are worried that the
culture and history of their world-famous neighborhood could be lost in the
process, and they have started a campaign to preserve its character. The city,
meanwhile, is spending $100,000 on a plan aimed at keeping the area’s gay
identity intact.

Heterosexuals “are welcome as long as they understand this is our
community,” said Adam Light, a leader in the Castro Coalition, a group formed
eight months ago to address the shifts in the neighborhood in recent years.

And we all thought increased diversity was a good thing.
