You are badly and sadly misinformed Doctors do not mislead parents into sex assignment Parents have assigned sex to infants at birth for all of human history and certainly do not need doctors to do it These days as well as in the s doctors assist parents to assign sex when it isnt obvious by inspection and i have no idea on what grounds you describe that as misleading parents And you have it exactly backwards when you claim that underdeveloped countries dont have gender dichotomies that is racist nonsense of the worst th century noble savage variety Go to any international medical meeting on this topic and you will hear heartwrenching stories about the cruelty and ignorance of how these conditions are handled by parents and societies in the third world Look at the european pediatric literature on the difficulties of dealing with middle eastern patients with these disorders or the australian literature on dealing with south asians Underdeveloped countries are not beacons of enlightenment on this topic many are just a colonization removed from infanticide an older and far more natural way to deal with ambiguous genitalia than surgery
