"Atheism is a belief in nonbelief."

piffle! That is just playing with words and defining concepts narrowly to suit your interests.
Besides, you'll find levels and varieties of atheism, just as you find many modes of religiosity (did I just coin a term?)

Some atheists vehemently oppose 'belief' while others simply say they choose to 'not accept' religious beliefs without more evidence. Others oppose 'religion' but not belief per se. Still others react to specific religious claims, but embrace some sort of Pan-Theism (much as Little Hawk suggests in many posts)...a lot of fundamental Christians would label him an atheist for not accepting God, Jesus and strict interpretation of the Bible)...

we can debate, but tossing "bumper sticker" type slogans around hardly promotes understanding.

(I hope you realize that, much as you said earlier, critiquing arguments has nothing to do with judging you as a person....I'd hope that we could, if necessary, conduct a more detailed debate over coffee and still smile at the end)

(to put it differently, I don't debate with fools that I suspect are not even trying and won't even hear me....I could point to threads I don't go near! *grin*)
