One cannot force man to deny his impression of reality, be this religious or not. Even a penetrating education is unable to do so. By consequence the conclusion has to be that this form of atheism is fully worthless. Perhaps you presume that agnosticism is a third form of atheism. Therefore I prefer to consider agnosticism as a variation of belief and not a form of atheism.
True atheism is more than only the denial of the existence of gods.
This denial goes inevitable accompanied by the fight against religions. By consequence it is dependent on this opponent. There is no other possibility than undermine the theological assertions and theories. But, when nowadays the theology gets a more modern and realistic character, the struggle against religion becomes a rather unreal undertaking for the atheists. Most of their objections get lost in the fog of post-modern theological thinking.
