I've heard dumbasses talk about how the Mongol Empire was ackshually good because it had religious tolerance and a good postal service.
Implying:
1) The Orthodox population of Orthodox Russia, Muslim population of Muslim Iran, and Buddhist/Confucian population of Buddhist/Confucian China needed tolerating.
2) That people enjoyed the postal service more than they enjoyed the company of their loved ones before they were slaughtered.
Have also heard people shill for the Aztec's universal education system (it was basically 100% religious indoctrination, folkways, and nationalism, it was the equivalent of Sunday school more than modern education) and for the Vikings being good guys striking a blow at those damned Catholics (who were minding their own business in their own lands).
