Successor ideology
"Successor ideology" is a term coined by essayist Wesley Yang to describe what he sees as an emergent ideology within liberal or left-wing political movements in the United States, Canada, and to a lesser extent other Western countries, centered around intersectionality, social justice, identity politics, and anti-racism, the rise of which, Yang argues, is degrading conventional liberal values of pluralism, freedom of speech, color blindness, and free inquiry. Proponents of the concept link it to an alleged growth in the intolerance of differing opinions, to cancel culture, wokeness, social justice warriors, and to the far left; Yang himself describes it as "authoritarian Utopianism that masquerades as liberal humanism while usurping it from within."
The thesis garnered support from some commentators around 2020–2021, with Roger Berkowitz linking it to a broader retreat of liberalism worldwide that is challenged from the left in the form of the successor ideology and from the political right in the form of illiberal democracy. Matt Taibbi called the ideas of those he associates with the ideology "toxic" and "unattractive". The concept has also come under criticism, with some commentators arguing that the term does not accurately describe trends within left-wing movements and others considering it a reactionary concept.
