Dude, I'm also an atheist and very vocal about it. Don't be that kind of atheist. Pick your battles and realize that trying to eliminate religious words from non-religious applications is not one you're going to win. This is really no different from atheists who refuse to do things like exclaim, "Jesus Christ!" when they stub their toe or are super frustrated or whatever as if the words have some sort of power.
As someone who thinks there is no such thing as the supernatural, maybe don't give words so much power?
