Do genes make people gay? If you put this question to Google, you'll find thousands of pages of Internet commentary on it, posted on the websites of fundamentalist Christian ministries, science blogs, and major newspapers. The reason why this question attracts so much attention is no mystery: Despite real progress on LGBT rights in recent decades, large numbers of people, both in the United States and around the world, still see homosexuality as wrong. But if being gay is inborn, rather than a choice, moral arguments against same-sex relationships become more complicated, because it's harder to condemn people for something that is beyond their control. It's therefore not surprising that the science of sexual orientation often winds up in the middle of moral and political arguments over LGBT rights.
