Atheism worships a dead god.

[Existentialist]

Sorry. Yes you're quite right. I didn't mean to be ambiguous, I didn't realize the ambigiousness of that sentence.

I meant not all atheists deny the possibility of any deity's existence.

Atheists are those who do not believe in deities. So that applies whether they merely disbelieve or whether they go further than that and in addition deny the possibility.

No problem. I assert there is no God. How I arrived at that assertion is less important to me than what follows from it. To me, an agnostic atheist is a contradiction in terms, an atheist atheist is a frivolous tautology.
