While Icke and all atheists disparage "religion" in all forms, I don't believe that belief systems of those that believe in a Creator versus those who claim there is not. It's the process, created by humans, that seems to be in dispute.
My question is: Does Icke (and then, other atheists) believe in an Absolute Good and/or ab Absolute Evil? If one is nihilistiuc and believes that there is no difference, then I will concede that there is no overlap between those people and those who believe in "God". My follow up question to them is "then why not run aruond pusning old people down flights of stairs?"
A belief in an Absolute Good is a belief in a greater power. Something instilled this morality into us. One doesn't have to believe in going to a building on Sundays or kneeling en masse to the sounds of loudspeakers to believe that there is indeed something more than just humanity.
