Some very interestingly developed arguments about how the GLBT community ought to be going about establishing civil rights in this book: "Love The Sin" reviewed by Michael Bronski in the Boston Phoenix.
Essentially, trying to establish civil rights via right to privacy and equal protection leaves us with the right to identity but not the right to public behavior. The authors' thesis is that a better approach is via right to practice religion since it's dual pronged strategy: right to *practice* who we are and broadening the scope of what constitutes "morally acceptable" as a theological basis for law. The fundies have too much influence. It's time for the rest of us Christians to have our say and be *listened* to.
