“In our time all Greece was visited by a dearth of children and generally a decay of population, owing to which the cities were denuded of inhabitants, and a failure of productiveness resulted, though there were no long-continued wars or serious pestilences among us…. For this evil grew upon us rapidly, and without attracting attention, by our men becoming perverted to a passion for show and money and the pleasures of an idle life, and accordingly either not marrying at all, or, if they did marry, refusing to rear the children that were born, or at most one or two out of a great number, for the sake of leaving them well off or bringing them up in extravagant luxury.”
-Polybius, Greek Historian
Anime was punishment for Hiroshima. We killed their city, they killed our birth rates.
When the men become weak and decadent with their pleasures, society falls.
Patriarchy keeps the men in line, to be men.
