“The rise of feminism is in direct proportion to the decline in the proper practice of masculinity by men.”
When I saw the article I said to myself “I already know the answer”. My answer is (a) masculine strength is less needed (power steering, pushing buttons, machines to do many manually-done jobs), and the pill which allows women to be less responsible and more agressive.
Your explanation fits with mine.
Also the value of a stable husband+wife+children family is giving way to men and women having careers, making money, not sticking with a mate they don’t like, letting others raise their kids.
Male children used to be of value to parents when they became men. Female children used to be valuable because they were the ones that eventually produced more children.
The nuclear family is now husband+wife+children+internet+cellphones.
Internet and cellphone...I love it (or maybe, I hate it...)
