Recent archaeological excavations in Greater Mexico City suggest the Aztecs, far from being a homogeneous people, were an aggregate of diverse groups who conquered their enemies without wiping out their languages and traditions. Yeah, just as long as the conquered peoples provided plenty of fodder for human sacrifices, the Aztecs let them keep a few folk songs and their language. Kumbaya!
Let me know if they discover anything about reparations while they're digging...
