To Kelly J. Baker, a writer and public scholar of religion and racial hatred, the attack felt familiar, and it made her nervous. Many rioters, a largely white group, were motivated by religious fervor and saw themselves as participants in a kind of holy war. Some brought Confederate flags, others crosses. Some who invoked the name of Jesus were members of far-right groups like the Proud Boys, whose participants have espoused misogynistic and anti-immigrant views. Some were motivated by conspiracy theories and QAnon falsehoods as well as their conservative Christian faith.
In many ways it resembled the culture of the Ku Klux Klan in the 1920s, and the group’s march on Washington in 1925, said Dr. Baker, who previously was a religious studies lecturer at the University of Tennessee. Many Americans associate the K.K.K. with white hoods, burning crosses and anti-Black racism but are less familiar with its white Protestant ambitions and antipathy toward Catholics and Jews. Dr. Baker explores that history in her book “Gospel According to the Klan: The KKK’s Appeal to Protestant America, 1915-1930,” published by the University Press of Kansas in 2011.
