It's too early for structure, so I'm going with bullet points.
1.) Not gonna lie, there are some things the Catholics have that I really wish I had. I'd love the solemn hymes, religious items in every store, and those beautiful cathedrals you mentioned. Don't blame ya there.
2.) I share Madhuri's confusion about committing before you're sure. I never really understood how someone could adopt a label, try to join a community, and talk as if they were a credible follower of a religion they aren't 100% committed to. It always felt better to me to just say I wasn't sure, or give myself a broad label like "Pagan" so that I could belong somewhere but not loose credibility or sound confused when I kept working out what exactly I believed.
3.) It sounds like you, as an LGBT person, are considering supporting an organization that largely condemns the LGBT community. I think this is fine, there are always sections that will accept you and they support other values you have, but I just want to remind you that only two days ago you argued with great fury and passion that it is not acceptable. I'm just pointing this out to suggest maybe reconsidering where you commit yourself, or useing this experience to understand how others can find themselves at peace in similar situations.
