^^..a mexican woman i know in touch with 'aztec' elders says something similar...that the spanish version of the human sacrifice story has been twisted, and manipulated to justify their invasion of a so-called 'brutal' people...it is true we only hear one side of this story..

below are images of an aztec descendant elder at a meeting with the dalai lama and shamans from around the world, from the film Fire on the Mountain https://www.youtube.com/watch?v=SsR8H0ZLncE (which i'll post somewhere else) ..go to 1:06:55 to see him in sacred pipe ceremony..
