I'm not here to tell you what's right or wrong....only the way the world works, and has worked, forever.
I don't care if the whites gave the injuns blankets with smallpox. I wouldn't personally condone that but I'm hardly going to lose sleep over what happened 150 years ago.
Like I said, you can read accounts of indian behavior written at the time and it's clear they were hardly angels. The popular modern ideal that portrays the indian as some sort of nature loving, gentle souls couldn't be further from the truth. They had plenty of deviant behavior. They killed each other at will. They lived in an area and when it got so filthy they started getting sick and dying they moved somewhere else. Even the Romans had plumbing. They were a greatly under-advanced society which lost out to a fiercer group of warriors.
