[FTR I do not go to a UM church, but have many Methodist friends, many who fall on both sides of this issue.]
Wasn't it the Traditional Plan the same "plan" that has been in place for a long while and reflects what's been written already in the Methodist Discipline? The way I've understood it, it did not create any new moral or doctrinal standards, right?
So if it was upheld, then there really isn't a change then, right? Yet there are so many upset about how the UMC has changed and hurt them. I suppose there was a lot of "loose enforcement" and "no enforcement" of the Discipline forever. But now with the old plan reaffirmed it really pissed some folks off.
No matter how the vote went, some folks are going to end up leaving. The "One Church Plan" is basically like a "State's Rights" government allowing each church (state) to make up their own minds about ordaining/marrying LGBTQ people. But if some did and some didn't that doesn't sound very "united" anyhow. Whether you believe it's okay to be/marry/ordain gays or not, find a place that believes like you do and be happy there.
