@Draug - I do not believe that your basic premise on the modifications are correct. You are correct that YJ said
"Below I have laid out some tentative parameters. If any are unacceptable to the opposition I would cheerfully negotiate modifications."
He then laid out complete parameters for the debate. Three topics, three moderators, off site, etc. It was very detailed and, IMO, rationally complete.
In response to this, Krellin said
If you want to debate, chase me obsessively around the forums, as you already do like some mental pervert, and answer me point for point there.
The term modify is almost always used in the sense that you are making minor changes to something. Krellin's proposal is not a minor change at all, but a wholesale trashing of one idea and replacing it with another.
Therefore, I do not believe that Krellin has actually offered up a modification of the above mentioned debate and, therefore, you cannot declare him the winner by default.
