Right now, gay pastors are kinda thrust in the role of gay activist. It's important and really brave, but I think it polarizes the congregation in a way that doesn't give the pastor the freedom to be about anything else. It's just the times we live in.
Metro churches feel like they're out of a different era sometimes, but I think we're seeing a time when the controversy is going to fade and gays and straights can worship together in ways that feel natural. Contemporary and emergent churches are getting to a point where they can't ignore the old-fashioned cultural views on gays don't line up with what they are preaching about Christ.
There's going to be some ugly kicking and screaming from traditionalists, but gay people are going to have more church options in the next 10 years.
