Hundreds of people came together Sunday to protest a controversial billboard in Richmond, Virginia which claims that “nobody is born gay.”

The billboard on Interstate 95 includes an image of identical male twins under the caption: “Identical Twins: One Gay. One Not. Nobody is born gay.” The billboard was erected by the ex-gay group Parents and Friends of Ex-Gays and Gays (PFOX), which promotes the message that gay people can – and should – change their sexuality.

People gathered at the Gay Community Center of Richmond (GCCR) for a photo shot in protest of the billboard.

“It's like we put out the gay Bat signal, and everyone showed up,” Robyn Bently, chair of SAGE, which advocates for LGBT seniors, told gay monthly GayRVA. “People are tired of gays getting bashed. Showing up was the right thing to do … this is a time of year when everyone's really busy and they showed up anyway.”

Bill Harrison, executive director at the GCCR, said that the photo taken Sunday might be used in a campaign to counter the billboard's message.
