You better check the definition of atheist in a good dictionary. You definition is insulting (don't worry. I'm not that sensitive).
If we are devoid of any responsibility, morals or ethic then by, the same token, I suppose those who believe in a God are the equivalent of crackheads living in fantasy land.
Since I never judged anyone for their religious beliefs - and in fact while being profoundly atheist, I make a point of insuring my daughter gets a proper religious upbringing - I'm inclined to disagree either way.
