It's a bizarre idea, isn't it? The default position seems to be whatever the majority religion is in your area. So you have to come up with "atheist" so that people know you're self-shunning. Even "secular" has a negative connotation in some places. "Destroyer of spiritual comfort" would be a loose approximation.

Even worse are the anti-theists like me (I guess I'd be an "anti-supernaturalist", but that doesn't really roll off the tongue). Not only do such evil creatures want to agitate people's comfort, they actively pursue the destruction of even the IDEA of the supernatural. What jerks!
