What it comes down to is this: The only argument I'm seeing here from the anti-gay crowd is this: "...Because the bible says so." They have yet to provide any compelling evidence outside of that statement; in fact, all the known scientific evidence is stacked against their position. The argument from the pro-gay crowd points this out. The argument from the Christian pro-gay crowd points out the fact that only a very superficial reading of the (pitifully few) texts dealing with same-sex behavior, only appear to speak against homosexuality. When a credible exegesis is actually applied, it shows clearly that any injunctions against homosexuality are unclear, vague, and, frankly, unwarranted -- and that the injunctions against homosexual acts likely do not stem from a thorough understanding of human sexuality. It's not even clear what kinds of homosexual acts are being referenced.
Nonetheless, the argument persists: "...Because the bible says so." When presented with clear evidence to the contrary, the tired argument only gets louder, with, perhaps, an added, "No, that's really what the bible says -- any idiot can read it right there!" Adding, perhaps, a weak, "God said it, after all."
Repeating "thebiblesaysthebiblesaysthebiblesaysthebiblesaysthebiblesays" doesn't make the argument any more compelling. First, there are many people -- gay or not -- for whom the bible holds no authority. So, even if the bible does say, its injunction only applies to those for whom the bible is an absolute authority. It cannot (and should not!) apply to civil law, or to social acts -- especially acts of systemic violence manifested in discrimination and judgment. Second, that's not the only thing the bible says. The overwhelming theme of biblical tenet is hospitality and equity. Why throw all that under the bus just to push a very minor point in the biblical milieu? Why continue to strain at gnats?
