Do you have any interest in theology in general?
Yes, as it relates to philosophy, ethics, and sociology. No, if it's just about the particulars of one interpretation of a religious text over another. I need a purpose - "unraveling the mysteries of God" or whatever higher power isn't an end in itself - I want to know how it applies to real life. And if I don't share enough premises with a particular theological argument, then the argument becomes uninteresting. The point becomes moot if it doesn't address my original issues.
I'm also interested in cults - but that's because of the psychology and extremes of manipulation. Interested in mythology, but that's as inspiration for storytelling and roleplaying games. Interested in traditions, sometimes, but that's as a basis for understanding cultural norms.
