Okay, just to make sure I've got this right. I want to know about your definitions of atheism. Like what specifically don't you believe in.
I don't believe in a biblical interpretation of God, as in, that guy with a beard who micromanages and controls our everyday lives.
I don't believe God is a physical or spiritual omnipotent reality either.
What I do believe is that "God" is an ideal and a moral standard to which we hold ourselves. I'm a religious humanist. To me, "God" is merely a useful term to describe an idealism that hopefully humans want to strive toward. To be godly instead of know "God."
The purpose of life is to understand yourself and your relationships with other people and with nature. Whether or not you believe in God is irrelevant; one should just attempt to be godly. This is still a Jewish theology that's widely accepted in more liberal movements.
My point being, it's highly possible that the more a-religionistic of us have condemned religion as being a horrible thing without properly looking at all of its more flexible aspects. Atheism and religion can coexist.
