The free will argument demonstrates that christians don't understand free will.

Don't you guys tend to consider heaven to be an ideal world?

Clever. Except you moved the goal post without addressing your unsupported premise that a god worthy of the name could fully conceive and create the fullness of reality free from suffering.

You're the one moving the goalposts. I should expect an all-knowing and all-powerful being should be able to conceive and construct, instantly and flawlessly, such a world, and to do so by expending no more effort than it takes for him to think about it. Your god has omni-qualities only when having them is convenient to your argument. When it's not, all of a sudden, he's got all of these little flaws, imperfections and incapabilities, things he can't do, rules he has to follow.
