It doesn't really sound anti-religious to me.

I feel kinda weird in these sorts of things because I'm a Faithful Xtian, so to me the kinda "anti-God/god" fiction is like someone saying bad and untrue things about my family. XD But then, I also prefer stuff that has NO real evidence of a deity one way or the other, beyond "This is what these people worship." The minute an actual deity gets manifested and all, I just stop caring. :/

(Which is why Reliquary has lots of supernatural goodies but will never have any direct divine intervention. It's more fun if things are left ambiguous!)
