Insufficient and Assistant,

European disease accounted for 90% (with estimates up to 95%) of Native American deaths

Far from all of that was accidental (Small pox infected blankets etc).
Beyond that there was plenty of rounding up and killing of the native population that remained after disease had decimated their numbers.
That Native American tribes warred with one another does not absolve their massacre and subjugation by an outside party.
We needn’t clothe ourselves in sackcloth and flagellate ourselves in shame over the actions of our ancestors, but we should not deny their sins either.

I await other articles in this same vein. Perhaps Mr. Kimball with your support could regale us with the equally valid arguments about why slavery in America wasn’t actually a bad thing for the Africans who were brought here and kept in bondage and how good it was for their decendants.
