In a word, I'm now a lot more agnostic about LGBT issues than I used to be. I have gone through phases where I've been opposed to gay marriage, but that ship has sailed.
I've never really had any secular case against gay marriage. I have made a religious case against it among fellow Mormons, but I've sort of lost interest in that now. I simply don't know what to think anymore. I really don't understand what God expects of those who feel the same way about their own sex as I do about the opposite.
I think legalizing gay marriage is a huge, complex experiment, and now I'm more of a spectator than anything. In fact, I don't even really follow the news on it anymore. I do still wonder sometimes what the long-term effects will be. Nobody knows.
As a Mormon, I think all kinds of casual sex are wrong, whether hetero or homo. I don't know about homo sex within a committed relationship—I'm now thinking it's simply not my issue or my business, so it's not a question I expect to have answered anytime soon, and I don't feel any pressing personal need to have it answered. I also no longer feel much, if any, need to shelter my kids from homosexual couple examples—that ship has already sailed, too.
So now my thought is: live and let live, good luck with your journey, I have no idea what the long-term results will be, and I don't understand what God realistically expects of gay people.
At the same time, I still don't think Mormonism should start performing eternal gay sealings in the temple without a specific, clear revelation. And if Mormonism did receive such a revelation, I would be confused because its entire theological system is based on eternal heterosexual coupling with endless spiritual progeny.
However, a Mormon bishop performing a gay civil union in a public LDS meetinghouse? Eh, whatever.
