I think interested readers will be impressed with this book and that instructors will be very tempted to assign it as a course text. There is a lively mix of authors—old, young, heterosexual, and gay—as well as a good mix of mental health professionals. A premise of this book is that most of psychiatry for the last 100 years was wrong about homosexuality. What passed for professional thought for many years was simply prejudicial, hostile, ignorant, and harmful to gays and lesbians, as well as unhelpful to mental health professionals wanting a better understanding of their difficulties. The authors address current trends and pressures to find a reductionistic biological explanation for homosexuality when, in reality, we are dealing with a more complex biopsychosocial phenomenon that varies across time and culture.
