Isle McElroy writes: “Last week, a debate erupted on Twitter over J. D. Salinger’s 1951 novel, The Catcher in the Rye. A person posted a video on Twitter calling Holden Caulfield a first-generation incel and proto–school shooter; defenders of Caulfield claimed he was a grieving abuse victim—a teenager!—who deserved our utmost sympathy. He’s part of an esteemed class of literary characters: troubled outsiders. He also isn’t real, a detail that both sides of the argument seemed to forget. Since he isn’t real, there’s nothing wrong with hating the guy. Nothing wrong with loving him, either.
