Same! I don't believe in astrology, but it doesn't stop me from finding it a fascinating set piece for creation. Things like that are actually very helpful when creating original cultures and settings as well. Doesn't stop it from having it's place in fanfic! Especially when you are making sure your background OCs are somewhat fleshed out so the world feels real. They believe and know a lot of things I don't, so time for more research on the subjects!
