America’s white supremacist Christian Identity churches preach the abhorrent doctrine that non-white races are the descendants of Cain, birthed through a satanic tryst between Eve and the devil.

We trace the pernicious origins and results of these ideas and consider why these ideas have been so destructive to western culture.
