TL;dr The economist and ethicist Itai Sher took issue last week on Twitter with philosopher Jason Stanley’s assertion (on Twitter) that “Fascism is always popular.” Sher asked (on Twitter) for evidence justifying the claim; Stanley replied (on Twitter) “it’s the main point of my entire body of work on the topic.” Things escalated, as these things do on Twitter, and Stanley blocked Sher, which of course just fanned the flames.
