What kind of study are you referencing there? I quoted a study commissioned by the Swedish government, which in turn referenced a study that looked at work culture in professions with unequal gender ratios.

Did you friends mention how children to men who take up female professions get teased in school because the job choice that their dad took? How their spouses don't want to tell friends what their partners job title is. How male nurses get question like "are you not a man, why are you a nurse?". People who walk up to a male midwife and accuse him of being a pedophile, ready to punch him? Read any of the multiple news article on how male preschool teachers do not feel safe at the job, feeling like they are under constant accusation by parents and co-workers? Same articles that talk how they dislike being the "representative" male, always chosen to do "male" stereotypical job activities?

But more importantly, the data don't lie. Male teachers and male students that are studying to become a teacher exit the job profession in rate about 450% higher than a female counterparts. Are we going to use the same old arguments that its something genetic that a male teachers starts working and after a year or so decide leave the profession?
