Cafeteria Christianity (2)

I recently heard someone say that on the subject of homosexuality, the Bible clearly says what it says. How, then, does it not say what it says on subjects ranging to slavery to the treatment of rape victims to remarriage after divorce? There must be some special Bible teaching, discernible only by the initiated, that says that the Bible counts only when it can be invoked against the unholy trinity of abortion, homosexuality, and modern science.
