That’s science talk for how Klan folk turn Ku Klux. Molly says it’s like an infection, or a parasite. And it feed on hate. She says chemicals in the body change up when you hate strong. When the infection meets that hate, it starts growing until it’s powerful enough to turn the person Ku Klux. Ask me, it’s plain evil them Klans let in, eating them up until they hollow inside. Leave behind bone-white demons who don’t remember they was men.
