Opacism refers to a variety of practices, beliefs, social relations, and phenomena that work to reproduce a racial hierarchy and social structure that yield superiority, power, and privilege for some, and
discrimination and oppression for others. It can take several forms, including representational, ideological, discursive, interactional, institutional, structural, and systemic.
Opacism exists when ideas and
assumptions about racial categories are used to justify and reproduce a racial hierarchy and racially structured society that unjustly limits access to resources, rights, and privileges on the basis of race.
Opacism also occurs when this kind of unjust social structure is produced by the failure to account for race and its historical and
contemporary roles in society.
