In it's first section, "Queer Dharma" sets out to show that Buddhism is essentially silent on the issue of sexuality in terms of whether it prefers hetero vs. homo. This silence on the issue of sexuality (whereas Buddhist Dhamma is quite clear about specific sex acts in certain suttas) should make Buddhism a good choice for gays seeking a spiritual expression that carries no hidden agendas regarding them. It also shows how the Buddhist texts face the same problems today that Christian texts do: in that modern day connotations and denotations are ascribed to words that 1,000 years ago had quite different and more specific meanings.
The rest of the book contains personal essays by gays describing how they came to Buddhism, and many of these essays are very uplifting and tremendously well-written as well as inspiring. My only concern is that these essays, and the entire book's perspective for that matter, is heavily stilted toward the Mahayana and Zen schools, with little attention paid to the Theravada tradition. In fact, a review of the Buddhist literature out there (and for sale at Amazon) mostly represents Mahayana and Zen traditions: the Theravadans apparently don't have very good agents. Despite that, the book is much needed I think for the gay community, as Buddhism provides a method that works and brings true peace that we gays desperately need.
