Like many civil rights movements in the past, disability culture challenges the norms of society, and seeks to counter oppressive entities such as medicalization and institutionalization. Its core values as a culture are reflected in art, conversation, goals, or behaviors. These core values often include: "an acceptance of human differences, an acceptance of human vulnerability and interdependence, a tolerance for a lack of resolution of the unpredictable in life, and a humor to laugh at the oppressor or situation, however dire it may be".[4]
