Um, I'm sorry, but I have to respectfully disagree. It's true that they barely said more than a few sentences about religion or religious-related topics, but they also have large 1 foot tall crosses up on the wall in literally every single room I remember being in. And it's not just an innocuous "t" shaped cross, it's the kind with an actual statue of suffering Jesus hanging on it. To people who are Christian, you may not even notice that type of thing, but to non-Christians it is a VERY prominently visible, ever-present indicator of who the school is meant for. While that may not even be the true intention of why those graphic crosses are on every wall, it does come across as a loudly passive-aggressive message to all non-Christians who are there.
That said, I actually liked the school quite a lot, and I really liked all the people there, they were all very welcoming and nice. But that's a different question. They don't "force" you to be religious, but the presence of Christianity at the school is very prominently on display everywhere you go.
