>>17828801 (OP)Islam is christianity, but why? Why did we need a second christianity at the time? It's because christendom is a civilization, not a spiritual kingdom, and christendom has limits. Look at the Armenian genocide, why didn't christians protect their own against the heathen? Islam was created as a response to weak christianity on the frontier where central christian authority didn't really exist. That's why islam is so obsessed with worldly matters and aesthetics, they're still trying to convert the physical world from a pagan hellscape to something worthy of christianity. Simply making everyone christian without enforcing the removal of paganism is a recipe for disaster.
