"This conspiracy theory version of the term is associated with American religious paleoconservatives such as William S. Lind, Pat Buchanan, and Paul Weyrich, but also holds currency among alt-right/white nationalist groups and the neo-reactionary movement.[65][56][66]

At Weyrich's request William S. Lind wrote a short history of his conception of Cultural Marxism for The Free Congress Foundation; in it Lind identifies the presence of homosexuals on television as proof of Cultural Marxist control over the mass media and claims that Herbert Marcuse considered a coalition of "blacks, students, feminist women and homosexuals" as a vanguard of cultural revolution.[55][64][69] Lind has since published his own depiction of a fictional Cultural Marxist apocalypse.

The Southern Poverty Law Center has reported that William S. Lind in 2002 gave a speech to a Holocaust denial conference on the topic of Cultural Marxism. In this speech Lind noted that all the members of The Frankfurt School were "to a man, Jewish", but it is reported that Lind claims not to question whether the Holocaust occurred and suggests he was present in an official capacity for the Free Congress Foundation "to work with a wide variety of groups on an issue-by-issue basis".

Adherents of the theory often seem to mean that the existence of things like modern feminism, anti-white racism, and sexualization are dependent on the Frankfurt School, even though these processes and movements predate the 1920s. Although the theory became more widespread in the late 1990s and through the 2000s, the modern iteration of the theory originated in Michael Minnicino's 1992 essay "New Dark Age: Frankfurt School and 'Political Correctness'", published in Fidelio Magazine by the Schiller Institute.[53][87][88] The Schiller Institute, a branch of the LaRouche movement, further promoted the idea in 1994.[89] The Minnicino article charges that the Frankfurt School promoted Modernism in the arts as a form of Cultural pessimism, and shaped the Counterculture of the 1960s (such as the British pop band The Beatles) after the Wandervogel of the Ascona commune.[87] The Larouche movement is otherwise mostly known for believing that the British Empire still exists, is trying to take control of the world (mostly, but not exclusively by economical means), and, among other things, also controls the global drug trade.

More recently, the Norwegian terrorist Anders Behring Breivik included the term in his document "2083: A European Declaration of Independence", which along with The Free Congress Foundation's "Political Correctness: A Short History of an Ideology" was e-mailed to 1,003 addresses approximately 90 minutes before the 2011 bomb blast in Oslo for which Breivik was responsible

Philosopher and political science lecturer Jérôme Jamin has stated, "Next to the global dimension of the Cultural Marxism conspiracy theory, there is its innovative and original dimension, which lets its authors avoid racist discourses and pretend to be defenders of democracy".[54] Professor and Oxford Fellow Matthew Feldman has traced the terminology back to the pre-war German concept of Cultural Bolshevism locating it as part of the degeneration theory that aided in Hitler's rise to power.[96] William S. Lind confirms this as his period of interest, claiming that "It [Cultural Marxism] is an effort that goes back not to the 1960s and the hippies and the peace movement, but back to World War I."
