Good Grief.
It is the Japanese version of ugly angry feminists griping about something.
There is a cure for their loserdom. Get out of the house, put down the cell phone, and talk to a real live woman. Might want to delete all those creepy pedo-anime cartoons too.
There are no real live women to talk to. Japan has a serious lack of young people in general and have an Asian tendency to desire male offspring as opposed to female offspring. Couple that with modern medical and routine abortions and you get lots of sexually frustrated men. There are hundreds of thousands more men than women of child bearing age.
China is in even worse shape. there are tens of millions more men than women due to an official one child policy. Japan only has a self imposed limited child policy.
Want to win the war against radical Islam and unregulated Illegal immigration? Have several children. Particularly in Middle Class families.
