I think you are seriously wrong in your position. First off, the "a" in atheist is not the same "a" is amoral. Atheists can have morals and values. They just do not believe in a religious icon such as "god". I am an atheist and I not amoral. I understand the position of christianity and I reject it as an unbelievable fallacy. Until proof of their god surfaces, I reject it. You cannot prove a negative.
All religion is based on faith. Militant Christians put faith-based over reality-based and I think that is where this problem started. If you said the world was round in the 1500s, you got burned at the stake as a heretic.
It would be funny to point out when you die, you end up as maggot food rotting in the ground. But it is not since more people have been killed in the name of God than all diseases in the history of the human race.
