“It can feel weird to be empathizing with someone you profoundly disagree with,” Marron said when we met, “especially in an age when people say you’re just as bad as them if you empathize with them. But all my guests . . . I think they’re just good people trying to do the best they can. We all have these really different experiences, different things that drive us to be who we are. That’s largely what divides us, and how we present that version of ourselves online is where all this comes from.”
