Christian schools are filled with idea-national socialists. Pretty much they expect you to believe what is being told and take it as if it is 100% factual. Really getting labeled as having extreme ideas (may not seem that way) in a structured and rigid system usually isn't a good thing to do. You can be mature, hold onto your beliefs, and not create a target so that other's can manipulate you or take you down.
I prefer Sartre.
