FDR called them Economic Royalists, and often warned that they would rear their heads again. Read: FDR’s Acceptance Speech
They did so in the early seventies, when some of them formed the Heritage Foundation to think-tank political strategies. Read: Are Economic Royalists Leading the US Over a Precipice?
The Heritage Foundation then formed various organizations for the purpose of setting their strategies in motion. One of these organizations was the (now defunct) Free Congress Foundation.
“Free Congress Foundation is politically conservative, but it is more than that: it is also culturally conservative. Most think tanks talk about tax rates or the environment or welfare policy and occasionally we do also. But our main focus is on the Culture War. Will America return to the culture that made it great, our traditional, Judeo-Christian, Western culture? Or will we continue the long slide into the cultural and moral decay of political correctness? If we do, America, once the greatest nation on earth, will become no less than a third world country.” (link)
It was the Free Congress that came up with the idea to frame “political correctness” as an ideology and liberal conspiracy to destroy Christianity and Western culture. Read: History of Political Correctness
Andrew Breivik further developed the conspiracy theory as Cultural Marxism and claimed that it targeted the white race specifically, with goals of Western Islamization. Read: The Breivik Manifesto
