It actually originated in Nazi Germany as "Cultural Bolshevism". However it has now become mainstream on the right and even popular among so-called liberals like Jordan Peterson.

According to wikipedia: "Cultural Bolshevism (German: Kulturbolschewismus), sometimes referred to specifically as art Bolshevism or music Bolshevism,[1] was a term widely used by Nazi German-sponsored critics to denounce modernist movements in the culture, particularly in seeking to discredit more nihilistic forms of expression. This first became an issue during the 1920s in Weimar Germany, when German artists such as Max Ernst and Max Beckmann were denounced by Adolf Hitler, the Nazi Party, and other German nationalists as "cultural Bolsheviks." Nazi claims about attacks on conceptions of family, identity, music, art and intellectual life were generally referred to as Cultural Bolshevism, the Bolsheviks being the Marxist revolutionary movement in Russia[2]. Cultural Marxism is a contemporary variant of the term promoted by psychologist Jordan Peterson which refers to the far-right antisemitic Cultural Marxism conspiracy theory."
