After having worked in a Christian school for several years I can attest that just attending one of those school doesn't make someone a Christian. Trust me.
On the other hand some of the most raucous rabble rousers were some of the most staunch Christians I have ever met. They didn't have to hide behind the thin veneer of 'niceness' which is sometimes confused with Christianity. My top leader of the prayer club was constantly in detention. For speaking her mind, for getting in peoples faces, that sort of thing. It all depends on the kid.
Oh and I like Renee Russo as an actress..old body and all.
