I feel that Marrk has such unreasonable issues with Gods laws on homosexuals in the church as not to notice that man has changed the laws and rules, but God who loves us all has still set the moral issues pertaining to marriage and eternal life. Those who choose otherwise are not lost to a Kingdom of God, just not the Celestial Kingdom... I have always taught that God will not embarrass us or make us feel uncomfortable, so in the Celestial Glory it will be only those who choose to have like minds and hearts and those in a lesser degree will be just as comfortable with like minded others...maybe a reason he can't or won't accept God Kingdom here on earth, and just as Marrk believes will be comfortable in a degree of heaven where his empathy for Gays will be noted and like minded.
For me, it's not about God's laws. God did not create gender, so the laws that govern procreation are natural. They exist outside of God's laws. Procreation can only occur between a man and a woman and so any other relationship is a perversion of natural law. God wisely established laws of fidelity. Those are not entirely natural. Both genders have a tendency to stray and follow lust rather than fidelity. That has to be guarded and protected. The continuation of God's work can only continue in this type of family relationship and that's why those who do guard it and protect it can be exalted where others can't.
However, there are a few statements you made that I would disagree with. I don't think it's appropriate to exclude anyone from the Celestial kingdom as a matter of principle or judgment.

There is no sin that cannot be forgiven but one. Acting on our weakness is not it. While it may not be possible to be exalted (as there is a limit to the time that the earth will exist - marriages cannot be performed in heaven so when this earth expires, so will the opportunity to be married) entrance into the Celestial kingdom is always open for those who repent - that is, if one believes that "though your sins are like scarlet, they shall be as white as snow; though they are red like crimson, they shall become like wool". If this is true, then the Celestial kingdom is not an opportunity lost. I see no time limit on this offer, do you?

I understand what you're getting. This is not to say that we won't feel uncomfortable ... that would be contradictory to wishing the mountains would cover us at his coming. But I don't think God assigns or judges us according to our comfort level. I don't think he puts us where we are of like mind. Rather, He puts us where we want to be and even though our minds are not aligned with those where we want to be, He affords us every opportunity to obtain that mind. Hence the ministering from those who are in a higher kingdom than our own. We are in that state now. No one living is like-minded with God. Not even those in monogamous relationships between a man and a woman. We are so far from being like him, much less thinking like him, that it will be a miracle that we will ever be even as he is. With that thought, remember that the opportunity for us lowly peons, to be like him, is still an open invitation. All we can do is be willing and obedient (Is 1:19) and for that (as little as that is), the promise is committed.
It is my personal opinion that this offer is never rescinded. If those who were once disobedient in the days of Noah have an opportunity to live according to God in spirit, then why not anyone else? Those who are willing and obedient now will be the ministering angels to those who were not. My question is, can God heal us now or must we wait? I think He can, even if it doesn't feel like He is. We may want to look back at what could have been, the fun we missed, the trouble we made because of the fun we had... it can all be healed and healed now.
I have a friend who served a mission and got married in the temple but decided that it wasn't right and dump his wife who understood - according to him - and pursued a same-sex relationship. He explained that he struggled with it and in prayer, he heard a voice that told him that if that's what he wanted, not to be concerned, he'll be alright and so he did. I have to believe that he will be alright, but at what cost? He will be so far behind where he could have been. He doesn't even see how far he's fallen from where he was. Sure, he's having a good time. He's successful. His home is beautiful and he's a great person, but he has issues and occasionally recognizes that something is missing. It will occasionally slip in comments that he can never have his own children and he misses that. Now set that thought on an eternal landscape and that void amplifies exponentially worlds without end. But he'll be okay. That seems to be an empty promise in light of all that could be, but I wouldn't divest him of Celestial glory just yet.
As I said, I don't know church policy concerning gays who are married and members of the church. I don't think any attend. I know gays who aren't married who attend and are quite active in church, but I don't know any practicing gays currently involved in a relationship who do anything more than an occasional visit as it is about all they can stand. I think that last statement says it all. I don't think practicing gays who disagree with church policy will agree with God's policy. I don't think they will be able to stand it which fits right into your comfort zone comment, but that's their choice, not God's and when and if they ever chose otherwise, I believe that opportunity will always be open to them as most of the work will be done for them if they are willing to accept it, but eternal marriage might not be within their grasp.
