Hypersensitivity is a pernicious way to win a debate: if you can brand an argument as offensive/harmful, then you never have to respond it. Trolling is a destructive response to that tactic: provoking more and more outrage undermines the credibility of your opponent. These are, I think, the twin central dysfunctions of political debate today, and that’s what I decided to write about for Times and Seasons this morning.
