"Professor Kingwell is obviously not actually proposing curbs on free speech, nor is he saying that people cannot be reasoned with or eventually come to be reasonable".

Um, yes he is, comparing the ned to regulate speech the way we regulate finance and business: " Let's go farther and insist on discourse rules, limits on public outrage and aggressively regulated social media. We could even ban media panel discussions...We'd still co-exist...But it won't be through talking things over, let alone hugging them out... let's have more constraint, less conversation. That's your path to a stable future, friends – by not trying to be friends."

Scary, particularly since he would be applying these rules to only one side of the debate. He uses those dishonest strategies himself.
