‘Renderings of stable, biological, binary sex don’t make sense under close scrutiny,’ professor writesUniversity of Pennsylvania Professor Beans Velocci published a book this year claiming “sex isn’t real” and the gender “binary” is “incoherent.” This identification has shaped the professor’s questions and conclusions because “that is how knowledge works,” Velocci wrote in the book titled “Sex Isn’t Real: The Invention of an Incoherent Binary.” Velocci claims in the book that “cisness” is unnatural and that people fitting into their “assigned sex category” took a large amount of work to construct and maintain. “Science continues to be an anti-trans ally,” the professor wrote, adding that sex has little to do with bodies, but is instead about categories and who controls them. “Renderings of stable, biological, binary sex don’t make sense under close scrutiny,” the professor wrote.
