It may be OT, but it made me think of something: Inequality of opportunity is part of what made the U.S. a 20th century powerhouse. Bright, educated women had two career choices pre-1965: nursing or teaching. (Even in 1960, the state school my mom went to did not accept women into engineering or architecture and she could only take higher science classes if she planned to teach.) All those bright women with no option…
Call me sexist, but I firmly believe there are three areas women should not generally be part of: military, cooking and teaching. All the best chefs are men, best professors I know are men too. And military requires more endurance that women normally have.
Anecdotal, but fairly true in my experience; when I did water polo in high school, it was coed. We didn't have many women interested in putting in the effort to land on the varsity team, probably for social reasons, but the handful that did were terrifying. I would rather have gone up against any two other people on the team than play polo with one of the women, because as it turns out there are certain things that guys just won't do to each other.
