I grew up in a christian household. My larents even went to two seperat churches (one service on saturday, one of sunday). They were very uptight about what was acceptable and what was evil. For example pokemon, star wars, yu-gi-oh, dragonball and harry potter were all forbidden for me. In my teens i became an atheist and never went back. Even though i do not believe in anything super natural anymore, i came to enjoy talking about religion with people again eventually.
If remember correctly she is never called super girl, but by her name (which i forgot, i am super bad at names)
