There would have been no genocide in the modern view if it weren’t for those crass, profit seeking, and bloodthirsty Europeans that invaded. They really need to take the responsibility for their actions. And the bulk of that genocide occurred before the US existed because the diseases those Europeans brought to the Americas that the existing inhabitants had no immunity to.
Genocide requires intention, the ginormous loss of life because of diseases is not, in a legal sense, a genocide. Not arguing that Europe colonizing the Americas wasn’t like a genocide, in some places it certainly was — but the people dying of disease is not a genocide, more like a mass-extinction event.
That is certainly a comfort to all those that died.
Probably not but a word like genocide shouldn’t be watered down, especially not if there are currently genocides happening intentionally in Palesta, Sudan and Xinjiang.
