Read the entire manifesto.  He is not against women being engineers.   As far as doctors are concerned. Are there more females becoming doctors because of sexism against males?  And guess what field has the most women?  Pediatrics (more that 50% female)  Which has the fewest?  Orthopedic surgeon.  Are those differences because pediatrics is sexist against males and orthopedics is sexist against females?  Or is it simply more females want to be in pediatrics and more males want to be in orthopedics?
