The oppression of various groups has taken place throughout human history. People are stereotyped, discriminated against, and treated unjustly simply because of their social group membership. But what does it look like when the oppression that people face from the outside gets under their skin? Long overdue, this is the first book to highlight the universality of internalized oppression across marginalized groups in the United States from a mental health perspective. It focuses on the psychological manifestations and mental health implications of internalized oppression for a variety of groups. The book provides insight into the ways in which internalized oppression influences the thoughts, attitudes, feelings, and behaviors of the oppressed toward themselves, other members of their group, and members of the dominant group. It also considers promising clinical and community programs that are currently addressing internalized oppression among specific groups.
