I see, I think, what you mean...
. Let's say you are correct, and it is indeed 'wrong' to think this. So, to continue your 'If God exists...' train of thought ... What if God WERE real, he Does Exist ... would any 'right' way to think about him even exist at all, from your point of view? If God exists, is it possible to think about Him rationally?
Oh, if He's a being with infinite qualities, there would be much about Him that's beyond comprehension. But the ID movement is driven specifically by an assumption about the nature of morality, not God. They deny that the real world provides us with the possibility of discovering any kind of objective way to judge one moral code or moral decision vs. another. I say we can look to the details of human nature to come up with good hypotheses for what the best moral codes are, and we can look to history to see what the actual results of various systems are. This is why, for instance, individual rights & the capitalist system are taking over the world instead of the various forms of collectivism.
But regardless whether God's mind is inscrutable or, um, scrutable, we would still know moral systems by their fruits.
