Al, we all know your stance on certain things (and I don't think God has gone new skool, so old skool is probably okay). I don't disagree with your assessment that gay marriage and homosexuality is morally wrong (note: but it's no more wrong than adultery, theft, etc. Sin is sin)...but...the hard reality is that our country's judges have typically chosen not rubber stamp the legislation of sexual morality except in the cases of prostitution and children. (and before you go down the abortion or stem cell road, these are TOTALLY separate issues).
But as a Christian, your primary mission is to use your faith as YOUR moral compass and to do what you can to increase the kingdom in a considerate and compassionate and loving way. Screaming sinner from the rooftop isn't what I think He meant. I strongly believe there will be a price to be paid for those who choose not to believe, but it's just that - a choice to believe and then to act.
There are millions who have not (and will not) made that choice yet, so their moral compass is not the same as yours or mine or any other believer. What our country's judges are doing, by following their moral AND legal compass, is keeping religion out of the system - exactly as our forefathers asked them to. As a judge presiding over this sort of thing, they first must ask, "Is there a legal (not moral, legal) basis to prevent this sort of behavior from becoming legal?" That's what they were sworn to do - uphold our Constitution. I'm pretty sure there's not a gay clause in that piece of paper.
That does not prevent you from expressing your opinion, and it shouldn't. You should continue to express and follow your compass direction. But while doing so, you need to understand that your compass is not the government's overriding compass. LEGALLY there is nothing to prevent gay's from marrying. And honestly, when looking at the tradition and morality of this it turns that thesis upside down in my head, too. But thankfully, our civil rights are not predicated on my tradition or morality.
Making gay marriage legal doesn't make it less of a sin in God's eyes. But when just about half of all marriages end in divorce and about 30% of men are unfaithful (inside and outside the church), I can't buy the argument about how gay marriage erodes family values. They already are.
