Like other white supremacists before him, the terrorist who opened fire at a Buffalo grocery store frequented by African Americans on May 14th published a manifesto beforehand explaining exactly why he did it. Nothing in that 180-page manifesto should come as a surprise to anyone who has studied racist attacks in America and other parts of the world over the past ten years. Sikhs murdered at a temple in Oak Creek for visibly practicing their faith. Black Americans murdered at a church in Charleston for simply being Black in America. Jews murdered at a synagogue in Pittsburgh for welcoming Muslim refugees. Latino shoppers murdered at a Wal-Mart in El Paso for representing America's diversity. White bystanders stabbed on a train in Portland for defending Muslim women from harassment. Young liberal activists murdered in Norway for supporting multiculturalism. Muslim worshippers murdered in places as distant as Christchurch and Quebec City for living in a white-majority nation.
