I'm saying that my concept of perfection may be flawed, but it does not mean that the underlying idea of what it means to be perfect is.
So the argument that "We don't understand God" to me is faulty because if we are created by God, given spirits by God, then it stands that we have a good grasp of what these things mean.
My argument wasn't that we don't understand God, though, should a God exist, I would think that highly likely. My point was that you are making assumptions about what such a God would do that are a) unsupported and b) do not have to apply to every possible god.
