The presented argument by analogy is stronger than the initial simplistic (and shaky and, frankly, silly *heh*) argument asserting “proof” that “God is evil.”
Of course, both arguments must rest on earlier arguments for the existence of God which aren’t presented here. But that’s a much longer discussion. 🙂
Note: the jury is out on whether or not Albert Einstein actually said this–different sites say yes and no, though I’ve yet to see it attributed to someone else–but I am almost 100% certain that the presentation of him having said it as a young student in argument with his teacher is pure fiction, presented as such for effect.
