Excellent summery ..Thanks for the clarification
Those who believe in traditional “free will” have just the same problem as they claim that Calvinism has.
If we believe that God created blindly with absolutely no sense of what was happening, but just sort of tossing it into the air, then even that does not remove Him from the charge of being the “Author of Evil.”
Even open theists would have to deal with the same accusation.
It isn’t just at Calvinists that it can be aimed.
