Great Replacement Theory Fear

The Fear engendered in White Nationalists by the Great Replacement Theory is perhaps subconsciously justified in their minds by their subconscious knowledge of what was done to the Native Americans by the invading Whites.  White Nationalists believe that if non-White people become the political power in America, then those non-Whites will do to them, the White Nationalists, what they, the White Nationalists did to non-Whites under their (the White Nationalists) domination.
