A single incident can't prove anything in terms of social science, but it can certainly serve as a vivid illustration. That was the case with the Buffalo massacre that horrified the nation and the world last weekend, which seemed almost inevitable in light of the new book "Radical American Partisanship: Mapping Violent Hostility, Its Causes, and the Consequences for Democracy" by Nathan Kalmoe and Lilliana Mason.
The Buffalo shooter's so-called manifesto, Kalmoe told me, consists of "partisan Republican media talking points," especially those of Fox News' Tucker Carlson, "along with the most radical elected Republican leaders." I wrote about the history of the "great replacement" theory last year, but "Radical American Partisanship" provides a broader perspective. "Our book talks about the long history of racial-partisan violence and how those two things are linked," Kalmoe said. "We don't know the shooter's media exposure so we can't begin to judge cause and effect, but we can say this is the kind of action you'd expect more people to take as explicit white supremacy, antisemitism and other extreme conspiratorial vilification gets mainstreamed among Republicans."
