Anders Behring Breivik described himself as a conservative Christian and he thought Cultural Marxists=multiculturalists=Islamization of Europe. This racist right-wing conspiracy theory is tied to the Islamophobic "Demographic Winter" thesis.
The concepts within cultural conservatism are a confluence of traditionalist claims from Europe and the United States. Major US groups send representatives to Europe, and there is a general meet up at the conferences of The World Congress of Families. See background here: "Exporting 'Traditional Values': The World Congress of Families."
Speakers at the WCF warned of a Demographic Winter at the WCF meeting in Poland in 2007. See for example, John D. Mueller, "A Family-Friendly Fiscal Policy to Weather "Demographic Winter.'" Left unstated but clearly understood, is that it is White people who face a "Demographic Winter" as the population of Muslims, Arabs, and other "non-White" people increases in nations. Breivik mentioned the
According to Breivik:
There must be more focus on multicultural doctrines (multiculturalism = kulturmarxisme) as it is this ideology that allows the political mechanisms that result in continued Islamization (Islamic demographic warfare). People must learn what multiculturalism...doctrines do with Europe:
European (a national) identity
Of course, it is known that kulturmarxistene and humanities in Europe think they are going to reform Islam but they will fail like all before them have done. We, for our part, the cultural conservatives and anti-Marxist liberal, must focus on the basic problem - multiculturalism (kulturmarxisme) and how to combat this...
A major theorist promoting the conspiracy theory of "Cultural Marxism" is William Lind. Lind addressed the right-wing group Accuracy in Academia in February 2000. See also: What is Cultural Marxism? by William S. Lind.
Apocalyptic Christian Belief and Islamophobia
Among right-wing Christians who fear Muslims there are some that see Islam as the false religion of the Antichrist in the End Times in their idiosyncratic reading of Biblical prophecy.
This apocalyptic view is widespread in some areas. For example a poll found that 15% of Republicans in New Jersey though President Barack Obama might be the "Antichrist" who is Satan's chief henchman in the End Times. Another 14% were convinced Obama was the Antichrist.
As Robert C. Fuller observed in his classic Naming the Antichrist: The History of an American Obsession, the candidates for the starring roles vary over time in fundamentalist eschatological analysis. Some see Islam as the religion of the False Prophet, the theological sidekick to the Antichrist. After the terror attacks on 9/11/2001 there was an increase in the demonization of Muslims in some Christian evangelical circles, especially those in which apocalyptic conspiracy theories flourish.
For example, Hal Lindsey joined in the Islam-bashing in 2002 with The Everlasting Hatred: The Roots of Jihad. Speculation in conspiracy circles that Obama is secretly a Muslim, perhaps born in Kenya, add fuel to this bigoted fire.
Paul S. Boyer, author of When Time Shall Be No More: Prophecy Belief in Modern American Culture, suggests that religious views about Biblical prophecy in the United States have “always had an enormous, if indirect and underrecognized, role [in] shaping public policy.” If the message of apocalyptic demonization is not clear, try reading one of the novels by Tim LaHaye and Jerry B. Jenkins in their Left Behind series of Christian apocalyptic novels which have sold more than 70 million copies.
Gershom Gorenberg blasts the authors because they:
"promote conspiracy theories; they demonize proponents of arms control, ecumenicalism, abortion rights and everyone else disliked by the Christian right; and they justify assassination as a political tool. Their anti-Jewishness is exceeded by their anti-Catholicism. Most basically, they reject the very idea of open, democratic debate. In the world of Left Behind, there exists a single truth, based on a purportedly literal reading of Scripture; anyone who disagrees with that truth is deceived or evil.”
The main villain of the Left Behind series of books, Gorenberg notes, is “Nicolae Carpathia, the man who turned the United Nations into a one-world government with himself as dictator,” on behalf of Satan. In fact, Carpathia is the dreaded Antichrist. According to Gorenberg:
Perhaps the most striking scene in the Left Behind series is the climax of book six, The Assassins [when] Carpathia is speaking at a mass rally in Jerusalem. Out in the crowd is [underground Christian resistance leader] Rayford Steele, armed with a high-tech handgun. He prays for God’s guidance, and finds himself firing what appears to be a fatal shot at Carpathia. Intentionally or not, this is an eerie rewrite of Israeli Prime Minister Yitzhak Rabin’s assassination at a Tel Aviv peace rally in 1995—but the authors are on the side of the fanatic killer.”
All of these conspiracy theories and more swirl through the Tea Party movement and beyond. LaHaye, before his novels, wrote a series of books popular in the Christian Right in which he laid out the master plan of the conspiracy of liberal secular humanists. Big government and collectivism was part of the sinister plan.
"Cultural Marxism," the Hoax Conspiracy Theory
The Frankfort School developed theories of "cultural criticism," and "The Culture Industry," but the term "Cultural Marxism" is a derogatory term developed by antisemitic conspiracy theorists.
So Breivik opposed "Cultural Marxism," the hoax conspiracy theory, but probably knew little of the actual "critical theories" of the Frankfort School, which are still used within sectors of modern sociology. See, for example, the work of Theodor Adorno and Max Horkheimer.
There are a handful of Cultural Marxist sociologists around the world who use aspects of the Frankfurt School theories, Flowing out of several strains of sociology are sections that use Race/Gender/Class analysis and include a few Cultural Marxists. So the real Cultural Marxism is an analytical lens used primarily in academia, not a global conspiracy to destroy Western Culture..
