Racism is evil, and to root its origin to monotheism is quite distressing!
Monotheistic Christianity, along with other monotheistic religions, has been blamed for racism together with other forms of discriminations this world can name. The practice of classifying people on different categories might have been with us even before monotheism was introduced in Israel, or say, in Egypt by Akhenaten in 1400 BCE, few years ahead of Sinai story. Accusation has been lodged, however, that the dawn of belief in “one and only god” inadvertently intensifies not only racism but all forms of discrimination. Regina Schwartz herself on her book, The Curse of Cain: The Violent Legacy of Monotheism, stresses this point which seemingly validates monotheism as the root of evil that has disintegrated us into warring factions.
