That's not refutation.
There can be only one way to understand 17:3.
THE ONLY TRUE GOD!
To spin it any other way digs yourself deeper into the hole, eg like how he tried to explain the each god acknowledges the divinity of the other.
Now not only it contradicts 17:3, it opens a can of worms that now there are 3 gods. Polytheism?
Spin it again and you hit a wall again whichever way you go. To put in effort to explain 17:3 shows deceitfulness and wickedness to play around with what you claim are God's words.
ONLY means ONE.
