>I agree that religion has been abused for power struggles, and other selfish reasons, quite often. But that, in itself, doesn't prove that no religious truth, no God, etc., exists.

But it does prove that what is presented as the word of god is often not the word of god. Therefore, anything presented by a revealed religion should be considered critically by the indivudual.

>Say, don't you think you should spell "God" with a capital "G"? Since you don't believe in God, this is nothing sacred to you, but in this context, the word is used a proper name.

Not necessarily. Take polytheistic cultures that don't believe in a single god.
