The atheist denies God not for God itself, but for what It implies of creation and order. In denying God, the atheist is denying the current order of things. It is absurd to spend time accepting or denying something that does nothing. The atheist wants to deny God because it is the cause of the current human order. Because he believes that there is a better one.
This order of humanity for thousand of years , the atheist thinks, is not a creation of God, as a consequence of God-created human nature, but an artificial result of the belief on It. To justify the existence of another better reachable order, the atheist invent a mythological, imaginary Golden Age in the past and an utopic future in which the atheism will return and perfect the golden age, when the actual order will be destroyed (Another world is possible). This hope in the transformation of this reality to a perfect reality, which includes a new man, is what impels it to deny God. The transformed superman of the future, of which he is an early model, is divinized. Whoever know Gnosticism, will recognize the pattern of a gnostic sect in atheism.
Therefore, the atheist is full of hate to the current order of things, but it is a hate based on a superiority complex over the ordinary people. They live in the jail of a perverted reality created by false belief in God and they are ignorant that don´t know and don´t want to know. He is also in the jail, but he knows it. Therefore, he feels superior, sanctified by himself and carrier of a holy revolutionary mission that since is based on an imaginary post-revolutionary reality, ends up in disaster and misery for himself and for the society. This blind hope is what distinguish the active and revolutionary character of the atheist from the passive, nihilistic agnosticism.
