Is Her Parents Overprotective?

[Sparkly]

My best friend can't really talk to me during school, so we talk on facebook a whole lot. But she let me get on her Facebook, so I put her profile as Castiel (from Supernatural) in a unicorn outfit, and her mom made her delete me as a friend, her father got upset with me, and they both said I cannot be friends with her. What is so wrong? Also her parents want her to be friends with either Christians or Catholics. I am neither. I told my friend about my religion, she said her mom would hate me, and she isn't comfortable with it but still is my friend. So now today she has unfriended me, and we can barely talk anymore.

Is her parents overprotective? Or is it just me. No rude comments or sarcastic answers.. -_-
Her parents made her delete me from her friends list.. So I don't know what to do.. We have none of the same classes, i'm not allowed to go to her house, we don't ride the same bus, I don't have her number anymore, im not her friend on FB, she has no twitter. What am I supposed to do?
