Dr. Hall's observation regarding subspecies of mammals is that two subspecies of the same species do not occur in the same geographic area. One subspecies proves to be more prolific than the other and wins the territory for itself. Dr. Hall concluded that the natural territory of a human subspecies is continental in scope. He warned that two different subspecies of humans will not co-exist indefinitely on the same continent. Ultimately one or the other will pass from the scene.
Territoriality is an imperative for man as it is for all other mammals.
European Americans know well that much of urban America and wide areas of the South have become the territory of another subspecies. Territoriality is central to understanding the future America. Let current trends go for another 50 years, and it is obvious that then the Southeast will largely be African territory, and the Southwest mestizo- occupied territory, with various urban enclaves in the West under the control of Asians. The answer to that is the fact that the future is already with us in many areas. America Balkanized is now a reality in southern California, southern Florida, and in other places all across the continental United States.
