When Lovecraft invented the blind idiot god Azathoth (as the human narrator calls it), he was likely just taking the Old Catholic/Aristotelian view of God and imagining what that might look like given the universe we live in. Azathoth maintains existence by sitting at its center surrounded by vast demonic dancers. There's a mediator, here called Nyarlathotep rather than Jesus or the Pope, who claims to somehow be doing Azathoth's will when he told humans to murder each other.

I mention this because we would not consider N's commands morally binding, even in that scenario. We consider hypothetical deities moral or immoral based on whether or not they agree with "arbitrary" rules like not hurting people unnecessarily, not the other way around. Nothing else in the 'philosophical' account of God actually has moral significance. Nor can it provide a foundation for the claims that it sneakily assumes.

So one big reason why I look down on Robertson's argument is that the charge he makes against atheists doesn't distinguish theism from atheism.
