Another word needed

Non-belief implies that theistic belief is the accepted standard and non-belief is a deviation from it. To my mind, that gives a lot of unearned and undeserved credit to the belief position. In fact, the word atheist does the same thing. It implies that theist is the accepted standard and atheist is a deviation from it.
That's because theism is the standard. Atheists have to deal with it. Some tried to get the coinage "brights" accepted... kinda backfired.
Any opinions or suggestions will be appreciated.
How about "anti-bull"? (I'm new, so I don't know if I can use naughtier words) :)
