Except you quite explicitly did. In plain english. And then double down and defended the genocide of Native Americans as just one of those things that has to happen and pointed to the economic prosperity of America and Canada as proof it was necessary.
I'm not touching the other stuff, but the fact that most people in the western hemisphere were going to die when east met west is true. Even if it was on the best of terms, disease was going to wipe them out one way or the other. Maybe,
maybe if we wait until we had a better understanding of the diseases and had some vaccines to give them
before we introduced ourselves we could have prevented it from being a genocide, but how would we even know to do that?
(and that in no way excuses how we treated the natives, which was 50% horrible, 45% apathetic and 5% helpful (at best), it's a shameful history. On the other hand, they treated their own poor like sh**t (for the most part) then too, but that's also not an excuse.)
