We didn’t kill millions, look into how many Indians and non-Indians were killed in combat, Mexicans, blacks, and orientals will be too hard to find numbers for so use whites and Indians.
Indirectly we did. Culture, disease and land grabs killed millions. Granted probably 80% were via diseases but there were millions dead over 300+ years. Stone Age meets Iron Age = death to people with limited immunity, no technology, no written language and still flint Knapping. On top of that they were less than United. Enemies teamed up with enemies to settle old scores They never had a chance and it’s history that is not in question. You want to argue with everyone. That’s ok. Your wrong but that is your freedom.
Your desire to label the 7th Calvary church - oops 7th cavalry of the US army was there to kill them (man women and children). They lost but in the end the US army, US government won. So it is what it is. Again no good guys in this historical truth. Complain all you want but it will not and never will end the truth. We eradicated those who refused to be pushed out.
Out of curiosity, why are you unwilling to see history as what it was/is? Personal ties, hold on a narrative, or just plain stubborn? I don’t really care and will not change you opinions but always interested in why the opinions get held so tight that partial truths won’t penetrate.
