Another extraordinary claim made in the complete absence of evidence.
Are you claiming that men and women don't have different preferences? Are you claiming that Iran, where 70% of engineering students are women, is less sexist than the US?
>Yet today, women make up 50% of graduates in those professions? Did something change in their genetics? Or did those professions just become less sexist?
So medicine, law, education, biology, veterinary science, and chemistry got less sexist, but philosophy, physics, and engineering didn't. That's your claim. That you've made, again, without a shred of evidence.
