On balance Native Americans are the worlds most successful mass murderers. They introduced us to smoking tobacco which has killed countless billions. There are more Native Americans alive today than when we first settled. We grew their population over time with industry and helped them to kill billions. It's all perspective I guess.
What's funny about this is that this is how SJWs think. They like to say we purposely gave them "infected blankets" when the truth is cross cultural contamination simply brought a disease they had no immunity to.

Its a valid thought, although I think at this point if you are still smoking tobacco you literally are killing yourself. All the countless numbers of people who die from smoking from this decade and on, shouldn't be put in with the countless who were killed before word had gotten out that it was cancerous. I say this as I finish up a cigarette myself, so its not like I'm unqualified to talk on the matter.
But to touch more upon what you have to say, it is kind of fitting for this to happen to us instead of some other nation. Predominantly white Americans have tried to help so many other races only to have the majority of those helped races turn around and bite us. Yes, I do not deny that white men were to blame for a lot of tragedies done to other races, but I also do not deny that white men disproportionately contribute back to those harmed races more so than the others.
