...and a revelation was announced in which those in same-sex relationships were offered full membership in the church, short of temple sealings and endowment for not-already-endowed members, and were to be given all the same callings anyone else in a non-temple marriage could have, I don't think it would have any bearing on whether I 'went back to the church'. I mention that scenario because I think it's the most likely eventual (WAY down the road) change in acceptance of same-sex couples, if any. But even if they started sealing same-sex couples and calling men and women in such pairings to apostleship (since surely women would be given the priesthood by that point, too, which incidentally I consider possibly more likely than my first scenario), I can't imagine that changing anything where the church is concerned. I've always believed that, but it's become increasingly clear to me.
I know this doesn't help any 'cause' of trying to pressure the church into changing its position or policy so gay people will come back to it in droves or so that current gay members who don't want to leave will have a cozier home in the church. What it would do is make it easier for me to just go and enjoy the community and positive principles, free to date guys and marry one if I met someone who was right for me, and play along for the sake of family and friends who might feel more comfortable if I were going. But I'm just saying...these are two separate--though obviously interconnected or related in certain ways--issues, and my views of the veracity of the church's collective and individual historical or doctrinal claims, let alone those of the Bible, don't hinge on it. *shrug*
