Not any more than saying He allows evil.
That's not comparable. The only way God creates evil under Reformed theology is by placing an artificial condition upon God. Of course Reformers don't do that, only critics do. How convenient. God has no duty to prevent evil from happening, yet upon hearing that Reformers believe God controls everything, critics immediately place that duty upon God. This is very different from God's nonexistent choices, if they are based on foreknowledge. Nothing need be added.
So, you are saying God can't allow free will but He can allow evil? Aren't you placing finite choices on God's repertoir? It's not His 'duty"; it's His will.
