This is an interesting video.
The term that Caleb Maupin is searching for here to describe the liberal, middle class, bohemian radical type of socialist who is a cultural left-libertarian is “modernist.” I spent several months this year digging into the intellectual history of modernism and its arrival in the United States.
Caleb is correct that modernism is not derived from Marxism or socialism. It is an aesthetic that originated in Western Europe in the late 19th century and is equally compatible with anarchism, liberalism, conservatism, fascism, etc. There were Right Modernists like Ezra Pound. It is also true that the CIA sponsored modernism and waged a cultural Cold War against the Soviet Union.
Modernists are people who elevate their anti-traditional aesthetic sensibility – expressive individualism, cultural liberation, cultural egalitarianism or basically their rejection of all forms of collective cultural authority – above religion, ethics, ethnic loyalty, etc. In the case of socialism, they prioritize individual aesthetic self-expression above economics, which is why they alienate the working class by taking hyper aggressive positions on polarizing culture war issues like, say, transgenderism. They are people who are more interested in screaming about “white supremacy” and “bigotry” and arguing about “black trans liberation” than in advancing an economic agenda that benefits all working class people.
Modernists repulse the working class who either 1.) drop out of politics altogether or 2.) who flee into conservatism. It is a global phenomena. The demise of the Labour Party in Britain is the clearest example of it. It also explains the rise and fall of Donald Trump. It is worth observing that even though Trump lost the election due to White suburbanites he made deep inroads into the Hispanic vote who were alienated by all the Antifa and Black Lives Matter violence of this crowd and their “Latinx” messaging.
