causes of atheism

i used to be an athiest, I was athiest cos I thort it made me smart....... lol yeh right I was stupid. I was also a athiest cos I thort I was above christians, they where brainless religous people to me. God put me strate (thank God litterly). thats why athiest always think they are right, they tell themselves they are smarter then christians. They arnt, they are blind, and I really do feel sorry for em, cos I know what that blindness is like. athiests you are BLIND open your eyes!

I am mildly astonished that there aren't more conservative atheists.

Their ethos is nothing if not social Darwinist and Nietzschean.  These concepts are far more defensible in an irreligious context than in a religious context, and I say that as an atheist myself.
