If you go to some of the more radical White nationalist sites like Majority Rights, you often hear that US Whites should be placed on the endangered species list by the US Fish and Wildlife Service. I agree, but the only question is whether Whites are Threatened or Endangered. I would say probably Threatened.
In the map above, Whites are in green. Those are the areas with a White majority in the US. Areas with an Hispanic majority are in orange. They include much of the Southwest and Texas, part of Washington state (!), part of Kansas (!), parts of Colorado, south Florida and an area around New York City.
Yellow are areas with a Native American majority. Those areas are mostly in Arizona, South Dakota and Alaska with smaller regions in North Dakota, New Mexico, Utah and Montana.
It is Blacks that White nationalists are most upset about. White nationalists are utterly terrified that Blacks are taking over the US. As you can see, they are only concentrated in the Black Belt, which closely follows the former cotton-growing region, and along the Lower Mississippi River. The Black Zone is in Arkansas, Louisiana, Mississippi, Georgia, South Carolina, North Carolina and Virginia with pockets in East Texas, North Florida, West Tennessee and around Washington DC, Detroit and Chicago. Truth is there are few large concentrations of Blacks in the US.
