Not op but I've seen the video they referenced and their account is accurate from what I remember and the whole debate is shown (it's actually a long video). There were preselected topics with time limits for each one. The way they picked who was up was a bit odd with them basically racing to the chair but the ones not up there could vote to stop the current debaters turn and let someone else take over. It was definitely interesting.

In that production he was pretty engaged and most of the time seemed to be putting out relevant, thought out responses.

That's not to say there weren't any gotcha responses being thrown around but IIRC (it's been a while) it was coming from both sides of the debate. IIRC, there was some one of the debaters was actually more ,than Kirk (provided I'm not mixing up videos, healthy distrust for my memory lol).
