The reality is that women were treated and viewed by most tribes as nothing more than property to be used as the men pleased. They were, for all practical purposes, slaves. The Muskogean Natchez of the U.S. southeast regularly killed the wives of upper-caste males when their husbands died. The Tahltans of western Canada, killed the male prisoners and enslaved the women of their enemies. Every pagan culture exalts itself and despises all others.
Racism is inherent in sinful man.
This was true of Indians as well. This hatred of outsiders is one reason for the difficulty in learning the actual names of certain Indian groups. They are so consistently referred to in pejorative terms, that it is almost impossible to know their true names. This race-based animosity was viciously displayed when outsiders were captured. This self-important disdain for others also extended to the white man.
