You have a pretty interesting background
. xD One question: Are you still Catholic?
Anyway, I'm also Catholic and I'm having no problems with it. The Bible said that God said that there are also other gods so Christianity doesn't actually deny Polytheism nor the existence of higher beings. Belief in one God doesn't need to make you feel it is forced onto you.
Remember, the people are mostly the ones who make it wrong, not the religion. It's good to be open-minded.
Well, I seem like a religious person now, haha. I don't actually call myself religious - I don't pray all the time, I don't often read the Bible, etc. I'm just faithful to God.
By the way, welcome!
