I met people on college campuses who were defining themselves as genderqueer to express revolutionary feelings, or to communicate their individuality; they were gender fluid without being gender dysphoric. This phenomenon may be culturally significant, but it has only a little bit in common with the people who feel they can have no authentic self in their birth gender.
