Taking the response in good faith I would assume that it's just showing the way the debate could go. It's rather constructive, whereas asking why repeatedly, seeking to arrive at a contradiction, is a fool's errand that may work both ways. Proof by contradiction is an important tactic to weed out misconceptions, but the strategy for communication is to find common agreement. Faith is a loaded term, so in effect the response opens up the meta level to your believes about faith. Indeed, I wouldn't go there out on a limb, either, if I don't have anything to add.
