So what did the PCUSA do about the issue?
What are some of the good points you think would be applicable in this situation?
The PCUSA had discussions about this for decades. We tried to get both sides to understand each other, to come up with ways of coexisting. There were projects to get people talking about it with individual congregations and within presbyteries. But none of it worked, because conservatives had a core belief that they couldn’t coexist in the same Church with anyone who accepts gays. We could be as a polite, as understanding, and as Christian as possible. It didn’t matter.
Various types of local option were proposed. But they all would result in gays being openly accepted in some part of the Church, and many of our conservatives simply could never accept that.
When it became clear that no kind of compromise would possibly help, we simply changed the rules to allow presbyteries (for pastors) and congregations (for ruling elders and deacons) to choose the candidates that they thought were best, with no specific constitutional rule about sexual practice. We understood that many conservatives would leave, and they have done so.
A few years later we changed the rules to permit marriage of gays. There are specific provisions to protect pastors and congregations that don’t want to allow it. But again, this isn’t enough.
Interestingly, many of the churches leaving recently are going to a denomination whose theology is basically about as liberal as ours. They accept the recent confessions, e.g. the Confession of 1967, which explicitly teaches the same principles of interpreting Scripture that we use. While they claim there are more general issues, the only difference I can see is that they don’t accept gays. I think this is a temporary denomination, that will reunite with us in a generation.
As to the situation of CF, I don't think anything you can do will bring real peace. We tried it, and it wasn't possible. We have one group that thinks the other is teaching something that is seriously anti-Christian. In what should be my home forum (Presbyterian) the majority of posters think the largest Presbyterian church is apostate. This is something CF can't fix. Having a few forums that permit acceptance of gays, and clamping down hard on attacks against it, may be the best you can do.
The most serious practical issue for me is that I really have no home forum. The majority of Presbyterians can't really use the Presbyterian forum. It's denominated by aggressive conservatives. The liberal forum is a bit too liberal for the mainline denominations such as the PCUSA. Not so much in its theology as in its interests.
Most mainline denominations have forums where the primary church can use it. ELCA, Methodists, Episcopal, etc, can use their forum. But PCUSA people can't really use the Presbyterian forum.
Good luck on your postings, but I think most of us know enough conservatives to understand where they're coming from. I do have conservative Christian friends, after all. I just think you're kidding yourselves, that no one can be consistently "literal", because the nature of the Bible doesn't support that, that you aren't consistently literal, and that in practice which passages you take as literal change over time as new developments such as acceptance of interracial marriage or gays stop being so new and threatening. I don't mean that I think conservative Christians are dishonest. Many are fine Christians who really want to serve God. But it's easy for one's biases to creep into exegesis, and I think they're doing so here.
Let me tell you a story. In another Christian site, someone described an event in the Russian Orthodox Church. A priest was tricked into conducting a gay marriage. When the bishop found out, he brought in a demolition team to destroy the church building. It had been irreversibly desecrated. What surprised me wasn’t that Russians would do that, but that many of the US posters admired their courage. To me this shows just what level of irrational emotion is behind this issue. It’s not just a disagreement about how we do exegesis.
