After the mid-1960s, white supremacy remained an important ideology to the American far-right.[47] According to Kathleen Belew, a historian of race and racism in the United States, white militancy shifted after the Vietnam War from supporting the existing racial order to a more radical position (self-described as "white power" or "white nationalism") committed to overthrowing the United States government and establishing a white homeland.[48][49] Such anti-government militia organizations are one of three major strands of violent right-wing movements in the United States, with white-supremacist groups (such as the Ku Klux Klan, neo-Nazi organizations, and racist skinheads) and a religious fundamentalist movement (such as Christian Identity) being the other two.[50][51] Howard Winant writes that, "On the far right the cornerstone of white identity is belief in an ineluctable, unalterable racialized difference between whites and nonwhites."[52] In the view of philosopher Jason Stanley, white supremacy in the United States is an example of the fascist politics of hierarchy, in that it "demands and implies a perpetual hierarchy" in which whites dominate and control non-whites.[53]
