Libby Adler offers a comprehensive critique of the mainstream LGBT legal agenda in the United States, showing how LGBT equal rights discourse drives legal advocates toward a narrow array of reform objectives that do little to help the lives of the most marginalized members of the LGBT community.
This book is a critique of mainstream LGBTQ rights litigation and campaigns, and presents a counterargument about what can be done within the system that would benefit groups left out of the mainstream movement.
If you're looking for a book that is grounded outside the system, this is not it and I'd recommend Against Equality. But if you're looking at the mainstream LGBTQ rights movement and feeling it's inadequate (or feeling its perfect and don't mind having that view challenged) then this is what you're looking for.
A must read for anyone interested in LGBTQ legal issues and theory, along with Normal Life by Dean Spade.
