In Cistem Failure Marquis Bey meditates on the antagonistic relationship between blackness and cisgender. Bey asks, What does it mean to have a gender that ?matches? one?s sex—that is, to be cisgender—when decades of feminist theory have destroyed the belief that there is some natural way to be a sex? Moving from the The Powerpuff Girls to the greeting ?How ya mama?n?em?? to their own gender identity, Bey finds that cisgender is too flat as a category to hold the myriad ways that people who may or may not have undergone gender-affirmative interventions depart from gender alignment. At the same time, blackness, they contend, strikes at the heart of cisgender?s invariable coding as white: just as transness names a non-cis space, blackness implies a non-cis space. By showing how blackness opens up a way to subvert the hegemonic power of the gender binary, Bey makes a case for an antiracist gender abolition project that rejects cisgender as a regulatory apparatus.
