The cup is either half full or half empty to the atheist.What do you mean by that? Most people would regard me as an atheist and I would not characterize myself by either phrase. But, then again, it may fit depending on your meaning.
Some atheists emphasize religious faith gone wrong, and some do not. I happen to think religious faith is salubrious to society, more often than not. I happen to think it as least as often animates the synapses, as it does to deaden them. I find Dawkins paradigm that religious instruction of the young is akin to brain washing cult training, at once silly and offensive. I myself have just not been blessed with the gift of faith; thus I am a near atheist.
I hope that helps.
