Negative responses came from outside the transgender community as well. Liza Mundy of the "Washington Post" thought the book exceptionally dull despite the potentially interesting topic. Psychologist Eli Coleman referred to the book as "an unfortunate setback in feelings of trust between the transgender community and sex researchers," and his colleague, Walter Bockting, wrote that it was "yet another blow to the delicate relationship between clinicians, scholars, and the transgender community." Kinsey Institute Director John Bancroft said the book promoted a derogatory explanation of transgender identity that would hurt many vulnerable transgender people, and that the book, which was written in a popular science style, did not support the material in a scientific manner. Psychologist Randi Ettner said of Bailey, "He's set back the field 100 years, as far as I'm concerned."
