I don’t care where they go, as long as they aren’t Lutheran. Some of them would join United Church of Christ churches, since many UCC churches have openly gay pastors and gay commitment ceremonies. I know someone who was an ELCA pastor, and he became a UCC pastor because he thought that the ELCA wasn’t pro-gay enough.
Some probably do it for political reasons. They're liberal Democrats and they can promote the Democrat party in the process of having a good time.
