52 Culturally Competent and Diversity-Sensitive Practice and Cultural Humility Age, Illness, and Disability While individuals are living longer, ageism continues to exist and is reflected in negative stereotypes and the marginalization and discrimination of aged indi- viduals. Individuals living with physical and mental illness and physical and developmental disabilities also face negative stereotypes, stigmatization, and being marginalized and discriminated against.

Intersectionality The notion of intersectionality expands students’ cultural competence by explor- ing the multiple identities that many individuals occupy. Some may exacerbate powerlessness and stigmatization, such as self-identifying as black and being a member of the lesbian, gay, bisexual, transgender, and queer/questioning (LGBTQ) community, while others may place an individual in a contradictory position as both privileged (a professional social worker) and marginalized (a Latina woman living with a physical disability).

Critical Race Theory This perspective addresses the ways in which racial groups of color are sys- tematically disenfranchised. The focus is not on the biology of race, which
