Words on Fire: The Power of Incendiary Language to Provoke Violence and Restoring Respect in Public Rhetoric, Garcia Helio Fred

The book includes a history of such rhetoric, and identifies a playbook consisting of twelve forms of communication that typically precede genocides and other acts of mass violence. The Nazis used all twelve; the Rwandan Hutu used ten. Trump uses all twelve. The language triggers lone wolves to commit violence. Since 9/11 the use of rhetoric that provokes violence has been known as stochastic terrorism, a phrase that tends to confuse and that makes discussion difficult. The author suggests a more accessible name: lone-wolf whistle violence, on the model of dog whistle politics. The book draws on the most recent scholarship on lone wolves, their mindset, and what it takes to activate them to commit violence.
