The ex-gay group Parents and Friends of Ex-Gays and Gays (PFOX) is standing by a controversial billboard it has erected in Richmond, Virginia, which shows what it claims is a photo of identical twins, one gay and one straight, to prove that “nobody is born gay.”

Not only is the science behind such a claim shoddy, but the gay stock-photo model featured on PFOX’s billboard does not have a twin sibling.

Greg Quinlan, PFOX’s conspiratorial and extremist spokesman, defended the billboard in an interview today with the far-right outlet WorldNetDaily, insisting that that his group just wants gay people to know that “the truth that homosexuality is destructive to someone.”
