It's a tough red pill to swallow, but it's important. Women are just as important as men, if not more important, for any cultural movement.
"Stark argues that the rise of Christianity in the Roman Empire owed a great deal to demography. He asks how a tiny despised band of forty Christians in AD 30, the ‘Jesus movement’, could become a 6-million-strong subculture by AD 300. Conversion was certainly important, but demographic forces were arguably more vital. Christianity’s family-centred ethos sharply contrasted with the more macho, promiscuous ethos of pagan Hellenism. This had two effects. The first was to boost the Christian birth rate above that of the pagans, the second to attract a disproportionate number of female converts. Women’s role in socialising the next generation means that a female-dominated sex ratio leads to a disproportionate number of Christian children. In addition, Christians cared for their sick during plagues, dramatically reducing mortality. Higher fertility, lower mortality and a female skew in the childbearing age ranges endowed Christians with a significant demographic advantage over pagans. Even a small edge can rapidly increase a group’s share of the population over several generations. This happens through compounding, as more children beget more mothers, and so on in exponential fashion. Over several centuries, this has impressive social consequences. A Mormon-like rate of increase of 40 percent per decade, sustained over the period AD 30–300, is all that was needed to create 6 million Christians from forty original converts. In the year 312, the Emperor Constantine adopted Christianity as the official religion of the Roman Empire. This political act prompted a massive expansion of Christianity, but it is unlikely that Christianity would have been adopted if it had remained the creed of a tiny band."
From the book, "Shall the Religious Inherit the Earth?: Demography and Politics in the Twenty-First Century."
It should also be noted that Christianity, as well as other religions, continues to benefit to this day from what might be called "fertility injunctions," for example:
And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth,
Lo, children are an heritage of the Lord: and the fruit of the womb is his reward. As arrows are in the hand of a mighty man; so are children of the youth. Happy is the man that hath his quiver full of them
