Much of the commentary of “it’s not a real debate” or “it’s not good faith” feels like an attempt to disqualify him for violating some technicality about how a “proper” exchange of ideas should occur, eliminating the need to actually respond to opposing ideas. A type of “no true Scotsman” fallacy.

The fact is, he facilitated many frank exchanges of ideas. Whether he was willing to change his own mind during them is immaterial. Anyone could discuss any topic with him, and arguments needed to be made by both sides in front of an audience that observed and evaluated. Those sorts of interactions are the lifeblood of a pluralistic liberal democracy.

Imagine if Trump refused to debate for the presidency? That would be terrible, regardless of the fact that no presidential candidate would meet any of your standards for “good faith.”
