Did anyone ever actually think there was a gay gene-- more accurately, allele? Homosexuality clearly has a genetic component, and we've known that for decades. But we've also known for decades that most traits are not controlled by a single gene and that human sexuality is not a binary matter. This seems like describing a launch to the ISS with the headline "No firmament".
