**A *NEW YORK TIMES* BOOK REVIEW Editor’s Choice/Staff Pick** **One reporter takes an immersive dive into white supremacy’s explosive online presence, exploring the undercurrents of propaganda, racism, misogyny, and history that led us to where we are now.** Talia Lavin is every skinhead’s worst nightmare: a loud and unapologetic Jewish woman, acerbic, smart, and profoundly antiracist, with the investigative chops to expose the tactics and ideologies of online hatemongers. *Culture Warlords* is the story of how Lavin, a frequent target of extremist trolls (including those at Fox News), dove into a byzantine online culture of hate and learned the intricacies of how white supremacy proliferates online. Within these pages, she reveals the extremists hiding in plain sight online: Incels. White nationalists. White supremacists. National Socialists. Proud Boys. Christian extremists. In order to showcase them in their natural habitat, Talia assumes a range of identities, going undercover as a blonde Nazi babe, a forlorn incel, and a violent Aryan femme fatale. Along the way, she discovers a whites-only dating site geared toward racists looking for love, a disturbing extremist YouTube channel run by a fourteen-year-old girl with over 800,000 followers, the everyday heroes of the antifascist movement, and much more. By combining compelling stories chock-full of catfishing and gate-crashing with her own in-depth, gut-wrenching research, she also turns the lens of anti-Semitism, racism, and white power back on itself in an attempt to dismantle and decimate the online hate movement from within. Shocking, humorous, and merciless in equal measure, *Culture Warlords* explores some of the vilest subcultures on the Web-and shows us how we can fight back.
