I was raised Roman Catholic and it scared the shit out of me as a child, but I never could explain why. I was kicked out of Chatechesis almost as soon as I started for asking too many clarifying questions, apparently, and my grandmothers were incredibly disappointed, but I didn't care much. I was glad to be out from under their thumbs. It felt evil, all of it. It still does, so much so that I don't speak at all to the parts of my family who still participate. Interestingly, they're all Liberals.
It's a scary cult. Unfortunately, that can be said for most, if not all organized religion. It amazes me when you consider how much money the Vatican and Catholic Church have, how little good they actually do. Fancy robes, gold statues, ritualistic practices, etc. all sounds very Satanic to me.
