Compromises are useful when you want something. When your side is about to win you don't blow up the organization unless you have a mental problem.
Also, from what I can tell the gay bishops voted for the compromise. If they thought it was the right way to handle it, I am not going to shame them for it.
We will see if they make good on it next year.
The examples listed are examples of violent victories not political ones. Even then, they imply backtracking instead of maintaining the status quo until victory.
This was not a change in policy, it maintained the existing one, so that they could finalize their "divorce" amicably. There is a ton of properties as well as pensions involved. Properties that the UMC technically owns but was paid for by local congregations.
It might be worth noting that those gay bishops that I mentioned aren't actually allowed under current church rules. If they forced the issue and the conservative churches brought them to court instead, there is no telling what the courts would decide. Making deals was likely the smart choice, even if it meant waiting a bit until they start offering gay marriages to their parishioners.
