Well first off, being libertarian, I do believe in theory the state shouldn't be involved in marriage at all. In practice the state is involved in everything, though, because it's America.
Anyway, my opinion is...it doesn't matter. While I'm against gay marriage, I think we have a lot worse issues to care about than gays marrying, as far as societal morality goes. I mean, I don't think gay marriage is a GOOD thing, but it only affects 5-10% of the population anyway. http://oca.org/reflections/fr.-lawrence ... y-marriage That was one of the best reasoned arguments I've read against gay marriage.
But, despite me not liking it and thinking it's bad, I think overall Christians and other religious/values type groups spend WAY too much time on the issue. I think the reason why is, it gives them something to feel better regarding their own sexual and relational sins.
Why are gays able to adopt? Because all the straight people, Christians included, are having illegitimate children. Like 30+% of children born now are from unmarried mothers. But how often do you hear Christian groups talking about this? f*****g never. Because they know someone, or have a son or daughter with an illegitimate child. So because they're guilty of said sin, you never hear about it. But since less people statistically are gay, they're an easy group to pick on/project their problems on. Same with divorce, you almost never hear sermons about how bad divorce is anymore in churches, because 50% of people are divorced! Just with gay people, all gay issues affect people less, it's just a theoretical issue for them, so with it being a theoretical issue, you don't have to compassionate like you would for real issues like illegitimate children or divorce.
So basically, I don't care. I do think at the very least, there should be no federal laws regarding gay marriage or not, it should be left to the states. I don't think it's a good thing but I hardly see it as the society ruining thing it's made out to be, compared to the REAL issues of illegitimacy and divorce. As far as gay adoption goes, well, that goes with illegitimacy, maybe if we stop having illegitimate children the gays won't have to fix our problems and be parents to these kids?
