The meme format doesn’t really work, but the joke they’re trying to make is that even though they did all these terrible things, it was never because of religion. In fact, they just didn’t give a fuck in what you believed in. Genghis even allowed religious figures to be exempt from taxation.
Honestly from the limited knowledge I have, Mongolians seemed to be the one of the chillest of invaders. They gave you a clear choice, let us rule you or die. And once they ruled you they allowed many freedoms that crusaders and colonizers didn’t. Their tactics were brutal and I think that’s why people see them as so evil.
