I think I’m confused about what you mean now. When the colonists first arrived, none of them were American, nor using the American flag as shown in the original picture, because it didn’t exist yet. They were specifically using other flags because they were citizens of other colonial nations. If your point is colonialism and the treatment of native people was bad, then yes of course you are correct. But if your point is that it was U.S. Americans doing it with an American government and American policies in place, then you are incorrect. Other places are unfortunately bad too, not just the United States.
did they leave after they took the whole nation or something?
