Firstly, obviously, since I don't believe in God, I don't blame God. My point was that it's manifestly obvious that there is no such God and all such claims are hollow.
You can espouse religion and God, these mystical, supernatural wonders as these great and magical things, but they did nothing. Why does God always do nothing? Why is your God so utterly pathetic?
Saying, 'oh, God didn't kill the soldiers' is just a get out clause. I'm certainly not suggesting he did. I don't think he exists.
But what *does* he do? You claim he's loving and mighty, but he's not by his own followers' testimony . He's utterly ineffectual and cr@p. His followers swear that they have person experience of God, that he appeared to them or intervened, yet he only does it when it's trivial and insignificant. He'll apparently rescue two believers from a forest fire, maybe, but not stop a genocide.
Humanism, on the other hand, doesn't claim to be magical or supernatural, so it's a bit ridiculous to complain when a stated human edifice fails to be magical or supernatural. But at least the 'power' it invokes (human beings) provably exist.
By the way, even if you claim not to believe it, PZ Myers wrote a pertinant repost against the Darwin=Nazism claim:
