Welcome, Sailor Mini-Moon! (That's what she calls herself in the English translation of the
Sailor Moon S movie, which my daughter has been watching over and over again for the last week or so.)
As a non-Christian, I have to say that once I started interacting with more Christians I gained a new appreciation for the variety and complexity of Christian views. I think it's easy for anyone to get the idea of a particular religion (even their own) being dogmatic and inflexible, but it's always astonishing what wonderful variation and thoughtfulness exists in every faith.
Good luck with your rediscovery of Christianity, and keep on fighting for love and justice in the name of the moon!
