This is an interesting article from 2016, published immediately after the Trump election, which references some of the criticisms of the Left that were raised by the postmodernist philosopher Richard Rorty in the 1990s. Rorty’s prediction was that by abandoning class politics in favor of cultural politics, the Left would push the working classes to the Right, as the working classes would come to recognize the Left as cultural enemies, and as unwilling to defend their economic interests.
I started noticing the same thing during the 1990s as well. But my “solution” was the polar opposite of Rorty’s. Rorty wanted to turn back the clock to old-fashioned liberalism of the New Deal era. Whereas I, then and now, wanted to move to a much further left position, i.e. a revolutionary left that recognizes neoliberals as the primary enemy, that understands that the “right-wing” represents a dying traditional elite and traditional culture, that rejects the statism of the Marxist Left, and that recognizes PC as a “left-wing of the middle class” ideology that is a fundamentally anti-working class and anti-revolutionary position.
An authentic revolutionary libertarian-left would not be about demanding more favors from the state or creating or more state activities (such as “single-payer healthcare” or “Green New Deal”). Instead, it would be about eliminating all state actions (from the county level to the international level) that undermine the self-determination of the poor and working classes (from zoning laws to the IMF and World Bank). Further, an authentic revolutionary libertarian-left would be unreservedly anti-imperialist (including opposition to so-called “humanitarian intervention” or “human rights imperialism”). The appropriate position on “social issues” for a revolutionary libertarian-left is the traditional anarchist one, i.e. individual sovereignty, free associations, voluntary communities, decentralized pluralism, bottom-up federalism and mutual aid (and not “political correctness,” “cultural Marxism,” “totalitarian humanism,” “progressive stacking,” or other crap.)
