I think anyone who's ever lived in a family understands the ways things we don't talk about can surface in other ways. It's about the importance of communicating and trying not to regret the choices you've made, and yet being open to revisiting your whole belief system.
Ministers who are not anti-gay are very rare in the South. They're banished in a way from their own religions. I have relatives in the ministry, so it's not caricature in my life experience.
