The Counter Extremism Project (CEP) reports weekly on the methods used by extremists and terrorist groups on the Internet to spread propaganda and incite violence. Last week, the January 22 Nashville school shooter’s manifesto, which was heavily inspired by prior white supremacist mass shootings and copied aspects of other manifestos, was spread via Google Drive, X (formerly Twitter), and Substack, and shared by several white supremacist Telegram channels, including an extreme-right meme channel, a channel that promotes 3D-printed weapons, and a channel affiliated with the Order of Nine Angles, as well as an accelerationist chat.
