What Causes Sexual Orientation? Genetics, Biology, Psychology

Book excerpt: The debate over "nature versus nature" continues over the causes of homosexuality. Is there a gay gene? Is there something about the way a child is raised that can "turn" her gay? Or is being gay simply a "choice"? Taking a look at the major genetic, biological, and psychological theories of the origins of homosexuality, this book asks questions about gender, gender identity, and sexual orientation that are at the center of gay people's sense of identity and their struggle for civil rights and acceptance by society. While for centuries homosexuality was considered a mental illness, a moral failure, or a biological disorder, gay people in the twenty-first century have the evidence of scientific research and their authentic experiences of happy and fulfilling lives to support the pride and sense of community that is their rightful place in the modern world.
