You make an interesting leap here.
For example, I don't consider Genesis 1-11 to be literal history. I wouldn't go so far as to call it a fairy tale, and I certainly don't hate God!
Others here would call it a fairy tale, but still don't hate God. They might not believe He exists, they might be ambivalent.
A few might hate God, but I've not heard any of them say it as far as I can recall.
Care to clarify who you mean? Who you think hates God, and why?
