This past week, The Atlantic’s David Frum injected a seemingly remarkable statistic into the increasingly heated discourse over the perceived popularity of Hasan Piker, the far-left political commentator and unsparing critic of Israel who streams himself talking for hours on Twitch, a platform most commonly used by video gamers.

(A day earlier, Jake Tapper had convened a panel to discuss Piker’s “checkered” past.)
