“Casteism is the investment in keeping the hierarchy as it is in order to maintain your own ranking, advantage, privilege, or to elevate yourself above others or keep others beneath you. For those in the marginalized castes, casteism can mean seeking to keep those on your disfavored rung from gaining on you, to curry the favor and remain in the good graces of the dominant caste, all of which serve to keep the structure intact.”
― Isabel Wilkerson, Caste: The Origins of Our Discontents
