Sometimes you can't say it better than the people who are going through it. From Andrew, who I will quote at length:
Moreover, far from nihilistically renouncing nature, the marriage movement aims at reclaiming the mantle of nature for homosexuals alongside our heterosexual peers and siblings and parents. We know now that same-gender attraction, bonding and sex is ubiquitous in nature, and almost certainly has some evolutionary explanation. We know too, experientially, that the love cherished by many gay couples is real and beautiful and deeply human. It is not merely "contractual" or "nihilist". It is organic, natural and completing. It is humanizing and it is civilizing. History is full of such relationships, and they stand proudly alongside their heterosexual peers. The reduction of these shared lives and loves to abstract sexual acts is itself a form of bigotry. It is an attempt to reduce the full and complex human being to one aspect of his or her humanness. It is, in my view, anti-Christian to speak of gays the way this Pope does. The Christian calling is not to guard ferociously the ramparts of the 1950s out of fear but to listen to the experiences of gay people - what the Second Vatican Council calls the sensus fidelium - and try to integrate their humanity into the structures from which they have been so cruelly excluded, with such horrible human consequences, for so long.
It is Rod's self-evident panic at the thought of such an integration that has made some of us sit up and take note. There is some lurking fear that if this form of being human is recognized as equal in the civil sphere, let alone the sacred one, then the entire edifice of heterosexuality and marriage and family will somehow be destroyed or undermined. I do not believe that in any way. And I don't think it's possible to believe that without, at some level, engaging in homophobia - literally an irrational and exaggerated fear that the gay somehow always obliterates the straight, or that 2 percent somehow always controls the fate of 98 percent. This is where paranoia and panic take over. It is where homophobia most feels like anti-Semitism.
Be not afraid, as Pope John Paul II kept telling us. Of what should we not be afraid? We should not be afraid of the truth about ourselves.
That last point about paranoia is key, and it really defines, not just anti-Semitism, but bigotry itself. The most laughable aspect of America's long war against racism, is the justification racist would always trot out--the specter of interracial union. I can remember being a kid and reading about black folks struggling for some small right, that, these days, we take for granted. So you'd have some black dude who'd been born a slave, in some one room shack, but had risen to become a lawyer, arguing for, say, school funding for black kids in rural Alabama. And then you'd see some bigot responding with, essentially, the following, "If we give the nigras school funding, they'll take our women! Do you want a nigra marrying yer daughter?!?!?"
I would read that and think, "What? The dude just wants some textbooks, WTF??" There's this great riff in Wattstax where Richard Pryor talks about Southern whites accusing a black dude of raping some white guy's wife. The guy brings out his wife and says something like, "The nigger raped her!" The assembled black folks look at the guy's wife who, let's just say is not Scarlett O'Hara, and go, "You sure??"
