NPR's All Things Considered explored how attacks like El Paso and Charlottesville are used to galvanize other extremists.
AMY SPITALNICK: You look at Charlotte. You look at Pittsburgh. You look at Poway. You look at Christchurch. She look at Gilroy. You look at El Paso. That is a level of violence and of extremist violence that we have not seen in years.
ALLAM: That's Amy Spitalnick, executive director of Integrity First for America. It's a nonprofit behind a civil lawsuit against organizers of the Unite the Right rally that turned bloody in Charlottesville, Va., two years ago. Spitalnick says hoods are a thing of the past.
SPITALNICK: These neo-Nazis and white supremacists have absolutely no shame about what they believe and their willingness to commit this violence.
ALLAM: In fact, they spell it out in the screeds they often post on social media before attacks. They name-drop earlier attackers, and in turn use language meant to inspire others to take up arms. Parts of the manifesto linked to the El Paso suspect read like a how-to manual.
