You can't argue with men like him, because he's not interested in the outcome of the argument. He's only interested in making you lose it, or fumble, or go on the defensive.
He wants to undermine you personally, because you've questioned him.
So you can go at it like knives all the live long day, but if you've any sense of integrity or fairness, he'll just wind you up.
Which is his goal anyway.
Personally, I would deliver as much of a killer comment as I could, and then block him.
