Is it plausible that had we left them alone long enough like the Christians had to sort their own faith out, they may have dedicated that kind of radicalism into a moderate islam reform? But instead due to outside pressure by larger forces that kind of radicalism was pushed outwards and embraced as a way to insulate the faith from changing while turning what would've been its revolutionaries into warriors to protect the nation from outside influence?
Could also be the people of Africa were a terrible bed for organized religion, which prevented Islam from spreading as far south as Christianity did north. Which meant that Islam ended up more concentrated and forming breakaway sects was harder to do with less territory?
I will always wonder where Islam could have faced a great reform, because it seems like that chance has long passed.
