The major proof of the inexisrence of God

[Tiberius]

Does atheism intend to remain a philosophic discussion between academics or does atheism see itself as an ideology meant to be spred between large communities?

Careful Josef, atheism isn't an ideology.

As people like Shermer, Hitchens, Dennett, etc say: "Atheism isn't anything". When you take it back to definitions, atheism isn't making a claim, nor is it a position you take on something. It's simply a default position when you eliminate belief in a God (which is the claim). Similarly, we don't have words for "not believing in tooth fairies"; the only reason there is a word "atheism" is because theism is so prevalent in society.
