I'm a straight person, too and joined this site to show support for the GLBT community, but it turned into something more. I've posted threads to the General Discussion forum a few times over the last few years and Soulforce has helped me get through a couple of things such as the death of my mother.
Soulforce is a safe and friendly space to discuss just about anything, whether it's a political issue or a personal issue you need help with.
I've never been religious so I can't identify with your crisis of faith, but I have a friend who might understand. I'll call her Mary. She's a devout Catholic who is okay with GLBT people. She disagress with the Church about other things, too, and doesn't like the current Pope very much. But somehow she has found a way to keep her faith while disagreeing with Church doctrine. I hope you can find a way too.
