Failure to believe in God seems to me akin to a failure of imagination and higher consciousness. I understand perfectly rejecting the church, not because of the ideology of Jesus Christ, but because religion was set up to control and limit the implications of true Christianity, and later even injected spiritual paternalism and authoritarianism and cultural genocide of the multilateral spiritual world that existed before they declared and waged centuries of war upon it. 

So why not just worship the great Goddesses Inanna or Artemis? They're pretty spiritually amazing, you know, and they stand for a lot of what we think makes civilization and culture and humanity worthwhile. Their wisdom and benevolence opposes the wickedness that despoiled western spiritual freedom in earnest starting 1700 years ago. Why atheism? Why not pick up something old, older than Abrahamism itself. Step back in time and recover the beauty that was wrongfully taken away by such extreme cultish exploitative men.
