This paper brings White supremacist extremism to reality with citations and points to “Western militaries” as organizations already infiltrated with this ideology.

Abstract
White supremacist extremism, also known as “right-wing” and “far right” extremism, is a broad label of convenience that lumps together, amongst others, white nationalist, neo-Nazi, anti-immigrant, anti-gun control, anti-LGBTQ and increasingly even misogynistic grievances. While its key tropes have gestated for decades, an underlying theme that has come to the fore in recent times has been the notion of what the French philosopher Reynaud Camus in 2012 called Le Grand Remplacement (The Great Replacement). This argument holds that white, Christian Europe has been overrun by masses of black and brown Muslim immigrants from North and sub-Saharan Africa. Since the refugee crisis of 2015, in which more than a million asylum seekers fleeing conflict landed on the shores of the European Union, white supremacist-friendly intellectuals, social media, political personalities and movements have sought to mainstream the Great Replacement motif within European societies.
