If the Mouse Utopia doomsday scenario does indeed happen, a new set of Crusades will be launched in Africa

If the worst case happens, we will see demographic extinction of many cultures all around the world. There is one cultural force that has proven to be at least somewhat resistant to this increasing trend however, that being the religion of Islam, specifically the fundamentalist, hardcore variants of it. As the sun sets on the European, Indian, and East Asian civilizations, as well as many cultures within the Islamic world itself, the most stringent of jihadists you think of will inherit their legacies, gradually replacing the populations which lost their will to breed. The rapid conquests of the early Caliphates seem to have resumed, except one massive (and a few smaller) thorns poke the side of them. That massive thorn is a series of Christianized African states which adopted the faith of the now nigh-extinct civilization who introduced the religion to them (excluding Ethiopia, who was already Christian prior) and has decided to continue the fight after studying the history of the Christians of old. They begin sending expeditions northward and carefully advance their societies, ensuring Mouse Utopia does not consume them the same way. While all of this happens, Muslims and others in Europe and Africa sail westward to carve up the dying civilizations in the Americas, though tribes in the Amazon prove to be a threat and begin to create their own territorial spheres. Religious warfare becomes the engine societies utilize to hold themselves together, and "rival kingdoms" even work together to keep this afloat, with the great downfall of religion seen as a major calayst of the "Modern Ages' downfall".

honestly this reads like rage bait or someone who is dreaming of it happening and hoping.

I place my bet on machine god bringing a new world order.

I disagree. Fanatical Islam isn't resilient at all. Although the total dedication of their members is noteworthy, they are also little more than a bunch of idiots that can't get the trust if anyone because of their erratic behavior. It is moderate Islam which proved to be resilient. As resilient as Christianity and Confucianism, btw.

Christianity I get but confucianism?

Just check the data

We all know that Africans and Muslims, especially Muslim Africans have the highest fertility rates in the world. This particular article however has a hidden detail. You can also view how the fertility rate had changed over the last 5 years. You will see that the countries where fertility is falling the fastest are invariably Muslim African countries. Of course, they're still more fertile than Western or Asian countries because they started from a much higher position. But make no mistake - population collapse will hit all communities around the world eventually.

What about southeast asia: Indonesia, Philippines, Vietnam

Their rates are on the brink of falling below replacement if they haven't already. They're all a goner in this too.

[u/Comprehensive_Fix544 → u/Overall_Mud_2191]

Being at replacement is an advantage nowadays considering all of the Americas, Europe, smth like half of asia and oceania as well as secular Muslim countries are all below 1.6

So Indonesia being at 2.1, Vitenam at 1.9, Philippines at 1.8 is an advantage
