It’s about time people started to understand that atheism is NOT a belief. It is the ABSENCE of belief. It is the OPPOSITE of belief.
The root of atheism is, of course, theism:
belief in the existence of a god or gods ; specifically : belief in the existence of one God viewed as the creative source of the human race and the world who transcends yet is immanent in the world
So, a-theism means AGAINST a belief in the existence of gods which is NOT the same as a belief that gods do not exist as christians (and some agnostics) like to claim.
