I just wanted gowld to clarify what, exactly, his/her point was, because it seemed to be rather incoherent. Was gowld talking about Native Americans? I honestly can't tell.
I think it's pretty obvious that they were talking about the "manifest destiny" genocide of native people, considering that "freeing up" that land was considered pivotal to "completing america's destiny". though i guess they could have been talking about the genocide of african enslaved people through forced labor. or the genocide of people in the Philippines during the Spanish American war, which birthed the American empire. lots of genocide to choose from, actually, so i guess your confusion is understandable.
