worldbuilding

Millenia ago, there was a great war within the galaxy. Three prominent nation fought for there wealth, dominance, and so on.

Federation, predecessor of now misogynistic empire, fought for there survival and resources.

In order to win the battle and war, each empire must deploy massive amount of soldiers. This lead to the near depletion of male population. To prevent complete depletion of male population, federal government start to conscript female population and search for measure which will produce soldiers in very short term.

Eventually, other two empire faced same problem. some choose to produce robot soldier which was very expensive but strong and effective. Some chose clone soldier, affordable and strong enough to hold off enemies.

Federation chose neither.

Federation was ****, they needed cheap and cost effective solution for their problem. And that was technology would be called gene-crafting.

It was a technology aimed to solve problem once and for all. the government at that time aimed to recreate human pregnancy system to that of rabbit. Short pregnancy period, lots of children.

They edited human to be more horny, in order to encourage citizens to engage sexual intercourse. Obedient to superior, in order to build a obedient army. and finally, Strong and intelligent.

That worked well for the first. many woman volunteered to the program to avoid conscript and gave birth to the would-be super soldier. Many boys and girls grew faster than average, far stronger and intelligent than average of normal human. They obeyed order, fought bravery, and died heroic ****.

Century after that, Something has gone off.

Birth of female baby skyrocketed, gene-crafted female intelligence saw decline in both intelligence and strength.

Scientists (who was also gene-crafted babies) theorized it as degradation of gene and called for gene-craft to fix this before this became catastrophic, and failed.

for few more decade, gene of female human degraded more and more, reduced them to weak, unintelligent hairless monkeys.

Male citizens felt that they need to protect what once was their equal and eventually, restore their degrading genes.

It made partial success. Male scientist were able to bring female gene to the level of normal human, and in this process male and female will be united by false sense of equality.

Whole woman-kind was saved by great and majestic man-kind. Woman need to serve and pleasure men in any way to return the favor.

That was what average woman think their "equality" is. Male and female is equal, BUT female are inferior and need to serve man.

This wretched warped idea will be the main stream of female culture, and rule them forever.

Male citizen was not so happy with this idea. they want their once proud partner and friend, lover, wife back. Not some **** species.

But at this point, there was nothing male do to. At this point, female population out number male population by 100:1. They basically worship man as gods, and there was nothing man can do

TL;DR

women become sub-human man-worshipper by accident while man became super human(like space marine or some time custodes of 40k )

man not so happy to be served , woman happy to serve.
