«At the Wenner Gren conference on gender held in Chicago, May, 1994... the gay American Indian and Alaska Native males agreed to use the term "Two Spirit" to replace the controversial "berdache" term. The stated objective was to purge the older term from anthropological literature as it was seen as demeaning and not reflective of Native categories.
