These so called negative atheists are nothing but agnostics. A true atheist would arrive at the gates of heaven -or hell and say; "I must have gone insane or got amnesia whilst in a VR system."
Similarly, a true believer would look even the most overwhelming evidence that no god exists and see it as a 'test of faith.'

I myself am what I call a true-hedonistic-atheist, meaning I realise (or believe that) life and everything is merely a product of universal laws, and any meaning we find in it is ALSO a product of universal laws. Nonetheless -I enjoy the hell out of it! smile
