The argument is based on a philosophical conception of God that, to be God, God has to be able to do anything. If God can create a rock so big He can't move it then His inability to move the rock is a limitation. If He can't create the rock then He is limited by His inability to create the rock.

I don't have a conception of God that He can do anything for He reveals that He cannot lie. He cannot deny Himself. He must punish sin.

And He cannot create a thing that would be greater than or equal to Himself. It might satisfy the unbeliever if you state that the question itself is like asking if God can create a round square and that it is a nonsense question but, again, the problem is unbelief and not syllogisms with these kinds of objections.
