Talia Lavin went undercover in white supremacist online communities, creating fake personas that would gain her access to the dark reaches of the internet normally off-limits to her, a Jewish woman. That research laid the groundwork for her book, Culture Warlords: My Journey Into the Dark Web of White Supremacy. Lavin talks to Sam about what it was like to infiltrate those online spaces, what she learned, and how white supremacy cannot exist without anti-Semitism.
