I think you completely missed the point of my post as well.
I was hoping to have a logical conversation here but it seems at least two of you are frothing at the mouth with God anger to the point that you can't see straight. Please re-read my post and reply with logic as if you're trying to understand a different point of view.
As RoboTimbo said, the anger is at people who make up a god fantasy and then expect others to not only believe it, but think such a god is good.
If you want logic, the problem is claiming that God is a perfected person, while also claiming that he does things which real people would find abhorrent to do.
One could argue that we're no more than mice to God, so the cruel things we do to mice, in order to gain knowledge or better the lives of humans, are similar to how God treats us, because our lives are less valuable to him, just as mice are less valuable to us than humans. Mice could pray all day to us to be allowed to live, and we'd still kill them off when they got in our homes and spoiled our food.
But that's not the LDS view of God. He's supposed to be loving, kind, care about us like a parent, and, in particular, he's supposed to be a perfected human, like we're aspiring to be.
The parallel to a parent letting his children fail, in order to learn lessons, falls apart, when the lessons are so brutal. Parents don't let their children starve to death or get cancer just to teach them a lesson.
It would require a massive personality change, for average humans to be able to watch their children endure that much suffering and not interfere--a personality change for the worse, not for the better. There's no logic in saying that a cruel, compassionless God, is a perfected human.
