‘The fringe didn’t disappear’: Expert explains how to combat online threats, antisemitic propaganda

Alex Goldenberg, an open-source intelligence and cyber-threat analyst, explains how online hate and antisemitic propaganda have moved from fringe message boards to mainstream social media platforms like X, Instagram Reels, and TikTok. He warns that platform algorithms amplify extremist content, exposing young people to figures like Nick Fuentes and Candace Owens without them actively seeking it. Goldenberg, who founded his own national security consulting firm Silent Index in April 2026, trains international law enforcement and intelligence agencies to identify emerging online threats. He notes that the Incel movement and the True Crime Community have inspired real-world violent attacks, including a June 2026 shooting in Montreal that left three dead. The article's framing relies on expert testimony rather than emotional language, maintaining a neutral analytical register throughout.
