The sexism aspect is more a reflected one (its an issue I have with a lot of Iranian films too). Khazak nomadic life is clearly not one where equal ops has been pushed, is hard and so on. Asa is denied a job because he cannot get married, we feel sorry for him because the film at least partially present Tulpan as being unreasonable (all the big ear stuff is about that). So in feeling sympathetic towards Asa, we are buying into the normalisation of a lifestyle which denies women any autonomy outside of married life. This clearly explains the lack of woman for Asa to marry, how many of his nieces will stay on the steppes, even if they are not picked up by Khazak Idol.
