Cute Anime Conquistador Gets History Wrong

Yep. This particular gem was found on the Nationstates profile of a prolific forumgoer. But off we go with evaluating the most dubious claims.

Cannibalism: While most pre-Columbian historians agree that cannibalism was integral to the sacrificial practices of the Mexica people, in a ritual form, the concept of systematic cannibalism in the Aztec diet day to day diet is dubious at best in sources and assertion, either coming from colonial accounts such as the Conquest of New Spain by Bernal Diaz, or by Marvin Harris' 'Cannibals and Kings' theory of an aristocratic cannibalism over the lower castes. Historian Michael D. Coe in 'Mexico' states that while "it is incontrovertible that some of these victims ended up by being eaten ritually […], the practice was more like a form of communion than a cannibal feast"

Teach Them To Read and Write: Oh man, oh God. The Nahua people possessed an elaborate writing system based around pictographs, which they employed in codexes carved on tizoc stone, or painted above deerskin and plant fibers. They had a mathematical system, and compiled annals and calendars.

Modern sanitation: The Aztecs had working and applied knowledge of aqueducts, which they employed to carry potable freshwater to Tenochtitlan, employed for cleaning and cooking. Notably, Aztec knowledge of hydraulics was also displayed in the complex canal and causeway system that held the capital of Tenochtitlan together.

And to think that I even like anime, myself.
