Privilege is defined as the unearned benefits/entitlements or lack of barriers assigned to an identity that society considers a "norm" and therefore dominant. Privilege and oppression are well-maintained social systems that are reinforced by binarized, normative hierarchies that categorize certain identities as superior (privileged) and their supposed opposites as inferior (oppressed) (e.g. male and female; straight and queer; cisgender and transgender, etc.). There are various forms of privilege, some of them tangible and others less so. One form of privilege, for instance, is the representation of one's identity in mainstream media and books—something intangible but nevertheless valuable in our culture.
