Those "God" words are merely figures of speech, which have worked themselves into the language. And that is all it should be--God does not deserve to be venerated or worshiped by anyone. If anything, worshiping or obeying that Almighty Lowlife Scumbag is destructive to society, whether or not He even exists.
Example: Christianity has started the First Dark Ages, and is causing many of society's hangups with sexual activity. It has wasted much time and resources--all the hours wasted at church or at Kingdumb Hells could have been spent improving life. All the Christianity-influenced laws have dragged people down, and even started many a war.
Islam is not much better. Until Islam got root on the Middle East, it was the most intellectual region on the planet. Then, Islam took control--they have gone nowhere since. They too are responsible for their share of wars and terror attacks (including trying to blow up a plane on Christmas Day). They are responsible for very oppressive laws in parts of the Middle East.
And, both are reprehensible for creating sexism. As for Satanism, I have no evidence that it has caused regional wars and widespread sexism and impedence on science.
