Book excerpt: The alt-right movement in the United States has actively been endorsing the use of left theory to achieve its ends—and with varying degrees of success. Tracing occasions where figures on the alt-right reference left theory, this volume asks if the alt-right’s reference of left theory is just bad reading, or are there troubling ways that certain types of left theory encourage such interpretations? What if the connections between left theory and the alt-right lie in the shared disdain for certain types of institutions, structures of power, and the status quo? Are there lessons to be learned in what can often appear as an overlapping desire to deconstruct concepts like truth, justice, freedom, and democracy? Drawing on the longer history of right-wing readings of left theory, this volume seeks to unpack these recent developments and consider their impact on the future of theory.
