No sex in school
People with common sense can deduce that humans fell into their roles because of the human instinct for survival. Evolution or god, whatever you want to believe, gave men and women natural biological abilities and instincts with which to use these abilities. This is why when men were building and leading a medieval society in England, men were also building and leading a society in feudal Japan. Simply put, men were given the natural physical strength, ability, and aggressive nature needed to do these things. Were there weak, lazy, unmotivated men in these times? Yes no one denies that but if you can show me a civilization built primarily by female labor, defended primarily by female warriors, and technologically advanced primarily by female inventions then I’ll buy your poorly written comic book for a dollar.
