Speaking for myself, I've been surprised since I got here at how inactive the boards are. On the one hand, we're a minority of a minority of a minority of a minority, so there's a limited number of people to be involved. On the other, there's a lot to talk about.
When I came onboard a few months ago, I was immediately suprised by the lack of deeper theological discussion, gay-related or otherwise. I'm pretty active on another forum, and it's almost impossible to have a good conversation about Christianity. Every time I try to strike up a conversation (or someone else does) it quickly devolves into "Is the Bible true?" or "Is there a God?", and frankly, I don't want to have that conversation over and over, especially not with people who've already decided that I'm wrong and are chomping at the bit to tell me I'm stupid. That is to say, I want to be able to start with certain things taken as read, and that's next to impossible on a board that doesn't specialize in religion.
As much as I recognize and respect the fact that not everybody here is a Christian, I'd love to be able to talk about my faith without having to start with the basics. The only thread around here in recent memory that deals with religion/faith/the Bible is one started with the purpose of poking fun. (And I don't mean that as an attack. Lord knows I'm in for some poking fun from time to time.)
