The USA is a settler colony which requires the elimination of the natives in order to take over as private owners of the land which had been shared in commons by the natives. If the natives exist there in great numbers, they can claim rights to the land, so they have to be taken out. The colonizers of the lands known as USA committed widespread genocide and enslavement of the natives in order to depopulate them, including intentional use of bio weapons. Other ethnic groups can't lay claim to the land so their populations being high doesn't really have the same problem as far as land claims go, aside from maybe New Afrikans although I don't think most USAians are considering that claim seriously anymore/yet.
