Postethnicity refers to having multiple, voluntary identities that are considered authentic rather than being defined by a single identity based on attributes like ethnicity or nationality. It recognizes that individuals belong to many diverse groups and aren't confined to one. As societal identities become more integrated and inclusive, it symbolizes a collective "we" rather than exclusivity between rigid groups. Postethnicity in the U.S. affirms an individual's right to self-define based on interests rather than prescribed attributes, reflecting extreme individualism. However, critics argue it is unrealistic to think others won't categorize and label people as group members.
