Whew...perusing this thread has been fun.
The reality on the gay marriage issue is that it's coming, whether you agree with it or not...once Pandora's Box has been opened, you can't shut it again, and now that advocates of gay marriage have gotten a taste of the freedom they desire they will not stop until they have gained the full breadth of it.
So to the people that oppose it on whatever basis, I say why fight it? Learn to accept it and move on. Continuing to fight it makes you no different than the homosexuals who continue to struggle with the truth of their sexual identity, only the thing that YOU are struggling with is accepting your own essential equality with every other human being, no matter how abhorrent you may view some of them to be.
Why do you fight it? Because you love holding onto the idea that as flawed as you may be, you're still morally superior to "those deviant faggots" (or whatever the en vogue persecuted group du jour may be), though these days you don't dare to use those pejorative words in public, a concession you have made to keep that comforting thought alive. You can't bear the thought of accepting the truth that nothing intrinsically separates you from the people upon whom you sit in judgment.
And deep down, you loathe the creeping thought that nothing will remain with which you may separate yourself from the "immoral". After no group remains upon which to judge yourself as being morally superior, what is left? Nothing but the actions of humans as individuals...and having already acknowledged to yourself (albeit begrudgingly in some instances) that ALL humans are flawed and essentially weak, that is an extremely unpleasant thought. That we might all actually share the same heart of darkness! The horror! The horror!
It's a spiritual immaturity. To borrow a Christian metaphor, you have to descend into hell, the heart of darkness, before you can ever ascend to the next plane. And that is a scary prospect, but true freedom IS scary. Empowering, yes, but scary at the same time (for what if it ISN'T all that we imagined?).
Very few people actually WANT true freedom...myself included. Though I SAY I want true freedom, I'm not arrogant enough to include myself among those who have attained it at this point. Maybe, though, that self-expressed humility is merely a false front for MY arrogance...maybe humility is MY vehicle for maintaining an air of superiority...who knows...lol.
Anyway, enough solipsism. Continuing to argue so vigorously over the morality of gay marriage when both sides are solidly entrenched in their positions is futile and will only degenerate into personal attacks and nitpicking over largely irrelevant points. The only thing that will change the views of either side is verifiable data. And that verifiable data is on the way, because advocates of gay marriage are not going to stop until they've won the day, which they eventually will. And then, if they turn out to be wrong and gay marriage IS an abomination, the opponents of gay marriage will have the luxury (or consolation prize, whichever way you look at it) of saying, "I told you so!" Small consolation, of course, but a consolation nonetheless.
Support the side you support and put your trust in the outcome...the proof will undoubtedly be in the pudding.
