"Remember that this is not an essential doctrinal issue." (This must have been written by an Arminian!)
"Not an essential doctrinal issue"? If this isn't, then nothing is. After all, we are only talking about 1)the nature of God, and 2) how He operates.
Nothing to see here, move along.
(Besides, the Arminians don't want to discuss this with us, else they would have invited us.)
