On March 15, 2019, an Australian neo-Nazi in Christchurch, New Zealand, began a livestream in a mosque parking lot. What followed were some of the most horrific images ever recorded.
The video, which would be shared en masse by keyboard Nazis across the globe, showed a 28-year-old armed to the teeth killing 51 people. Less than five months later, a 21-year-old Texan gunned down 23 people in an El Paso Walmart.
The two gunmen were examples of many terrible things: Lone-wolf terrorists killing on behalf of their race, the international spread of extreme-right ideology, the gamification of right-wing terrorism, and the use of livestreaming murder as a propaganda tool.
They were also examples of the relationship between environmentalism and fascist ideology: Both of the shooters left manifestos online meant specifically for propaganda and to inspire other shooters; both manifestos cited the environment as a contributing factor to their shooting spree.
