I am addressing a specific claim she made in her paper, quote in full. "Not surprisingly, it is extremely difficult to estimate the frequency of intersexuality, much less the frequency of each of the three additional sexes: it is not the sort of information one volunteers on a job application. The psychologist John Money of Johns Hopkins University, a specialist in the study of congenital sexual-organ defects, suggests intersexuals may constitute as many as 4 percent of births. As I point out to my students at Brown University, in a student body of about 6,000 that fraction, if correct, implies there may be as many as 240 intersexuals on campus - surely enough to form a minority caucus of some kind." This section of the essay is not tongue in cheek. She clearly states she's teaching this idea. This was John Money's response "To the best of my knowledge there is no publication attributable to me in which I suggest, as Ms. Fausto-Sterling puts it, intersexuals may constitute as many as 4 percent of births. Moreover, it is epidemiologically reckless to conjecture that on the campus of Brown University there are 240 students with a birth defect of the sex organs that would justify their being diagnosed as intersexuals, that is, hermaphrodites"
