I agree, but that isn't to say by definition atheist isn't problematic. To me, the term Hitchens popularized is far more accurate. Antitheist. If the Bible calls Moses and the Judges of Israel gods, which it does, then there were gods. If a god can be anyone or anything mighty or venerated, which it can, then there are gods. If the existence of a god isn't necessary for it to qualify as a god, which it isn't, then the millions of gods there is and have been isn't dependent upon the belief of said existence by atheists or anyone else.
If I pick up a stick that looks like a bone and proclaim it to be my god then it is a god. It doesn't matter whether or not you believe in it.
