Perhaps the real 21 century slaves in America are the racists, who have been taught a lifetime of norms from birth predicated on hatred, buoyed by the knowledge that even their countries icons, forefathers and presidents were like them, devout racists.
Even though instinctively they may be at odds with their learned behavior, they are culturally bound to an abnormality that overrides all sense of respect and fairplay . An affliction their friends, fellow citizens , societal demands won't allow them walk back or escape from. They are by birth indoctrinated and condemned by the history of their countries ingrained beliefs and deeds. Like it or not they are slaves to the expectations of a fraternity, a citizenry of unreasoned haters.
