a.k.a. alternative right
Seen online, this term refers to a "group" of American white supremacists, white nationalists, white separatists, anti-Semites, neo-Nazis, neo-fascists, neo-Confederates, Holocaust deniers, conspiracy theorists and other far-right fringe haters.

Historical perspective: The term "alternative right" was apparently coined in 2008 by Duke-educated historian Richard Spencer to describe right-wingers who feel deeply alienated, intellectually, even emotionally and spiritually, from American conservatism.
