Theatre can reflect and promote cultural diversity in several ways. Theatre of identity promotes a particular culture's traditions and point of view to both cultural insiders and outsiders. Examples include Yiddish theatre in New York and plays chronicling the African American experience. Theatre of protest objects to dominant cultures and demands that minority voices be heard. Cross-cultural theatre mixes cultures to find understanding, like plays adapting Native American perspectives. Keeping diverse theatres alive ensures healthy cultural debate in a society.
