D: D’Souza clearly isn’t interested in facts, so what kind of effect do you think you can have?
K: I’m under no illusion that I’m going to get him off Twitter. He’s got a very profitable con—I assume it’s a con. I do it for people on the sidelines, [for] people who aren’t already his fans but are confronted with people pushing his work directly or his arguments indirectly. It’s a way to serve as counterbalance.
D: Are you worried that you’re just giving him more oxygen?
K: Both D’Souza and Trump have a much bigger audience than I have. The millions of people who follow them are already going to see [their tweets]. It’s important to not just let them go unchallenged. D’Souza’s schtick was to say that no historians ever objected to what [he says]. So our lack of fact-checking was taken as at least our tacit approval. If we don’t speak up and challenge these untruths, then they have the floor.
Historians have the same kind of duty that scientists have to climate change deniers, that doctors have to anti-vaccine folks.
