Talk of guns and potential violence is rife on the encrypted messaging app Telegram, the conservative social media site Parler and on thedonald.win, an online forum that previously operated on Reddit before the company banned it in June after years of racism, misogyny, anti-Semitism and calls for violence.

It was the top post on thedonald.win Tuesday morning, and anonymous commenters saw it as a call to action: “We’ve got marching orders,” the top reply said.

Discussion in the thread followed about how most effectively to sneak guns into Washington, laced with occasional references to using them. . . .
