Anti equality arguments just get sillier and sillier

From Slate:

Judge Vaughn Walker raised [a] point with a lawyer defending California’s Proposition 8, demanding to know “how permitting same-sex marriage impairs or adversely affects” straight people’s marriages. The lawyer had this response: “Your honor, my answer is: I don’t know. I don’t know.” 

The problem here, of course, is that an honest answer—“your honor, we believe gay people will destroy the marital institution altogether”—would undermine the supposedly secular, animus-free nature of these arguments. In developing them, anti-gay activists began with a conclusion—gay people don’t deserve the rights that we straight people have—then worked backward, camouflaging each prejudiced premise with a supposedly neutral talking point. Under any kind of scrutiny, these theories instantly fall apart, revealing their bigoted, constitutionally impermissible core.
...
And yet the inanity continues full-throttle, because gay marriage opponents have backed themselves into the corner they’ve always dreaded. They can’t give up their quest now—but they’re barred from citing the explanations that they truly believe, deep down, to be correct. The result is the current tailspin of idiocy, a shifting argument with rootless standards roaming from rationale from rationale in a desperate attempt to find shelter from the storm of progress swirling around it. It’s a pathetic display, but not an unpleasant one to witness. Stripped of all logic and reason, the argument against gay marriage has been reduced to gibberish. Enjoy the babbling while it lasts.
