I associate with Muslims, atheists, Hindus, and a few from a religion I can't spell.<quoted text>You are a Christian. I have zero doubt your parents were Christian and their parents were Christian and so on for many generations.
Now your particular flavor of Christianity is a bit different, but the general denomination is the same.
If you live in America, your peers are also Christian.
I would be surprised if you had many Muslim friends. The way you speak of atheists, you clearly have no atheist peers.
How do I speak of atheists?
