A GENDERLESS FUTURE?
What were they thinking! In March, 2010 the New South Wales (Australia) Registry of Births, Deaths and Marriages sent Scottish-born Norrie May-Welby an immigration certificate listing her as sex not specified. The bureaucratic decision to allow May-Welby to immigrate without specifying his/her sex or gender came after an extended legal battle. As it turned out, May-Welbys official genderlessness was a way station in a struggle that continues as of this writing. Following intense publicity, the Registry backtracked, claiming it did not have legal authority to produce a gender neutral certificate. May-Welby is suing. Moreover, May-Welby is not the only person on earth who wishes to live gender free. Reporters Barbara Kantrowitz and Pat Wingert suggest that a growing number of people consider themselves gender neutral (Kantrowitz & Wingert, 2010).
Confusion about gender categories (Male? Female? Neither? Both?) seems to be perennially newsworthy. Take the case of the South African runner Caster Semenya. During the summer of 2009, she beat the womens 800-meter running record by several seconds. Although her achievement remained a good 18 seconds off the mens record, her breakthrough prompted complaints that Ms. Semenya was really a man. An international scandal erupted when the International Association of Athletics Federations (IAAF), track and fields governing body, barred her from competition until she completed a gender test.
A what? What on earth is a gender test? You might think it is simple to tell who is male and who is female. Indeed, sometimes it is simple. But not always. More than a year into this story the IAAF decided to allow Semenya to resume competition. In August of 2010 she won handily in womens races in Berlin, Germany and in June 2011 she came in third in competition in Oslo, Norway (Bolt Blitz in Oslo; Athletics, 2011). But the IAAF did not release the gender test results, rightly maintaining that these contain Caster Semenyas personal and very private health information. So we remain in the dark about what a gender test actually is and how, in this case, it gave the IAAF the information it needed to allow Semenya to resume competition (Caster Semenya, 2010).
Genderless Australian immigrants. Record breaking runners who may not really be women. What then, are we to think about the future of gender? Is it really disappearing (I doubt it); should there be more than two legal gender categories (possibly); do we know enough about sex and gender to deal intelligently with the idea of a genderless future (no)? After all, dont chromosomes that join together at fertilization fix sex and gender for a lifetime (no)? Dont societies all think (more or less) the same way about sex and gender (no)? Have they always thought the same way about sex and gender (and no again)? Perhaps there are things about sex and gender that we can never know. And if so why cant we know them? These are among the questions this book addresses. Perhaps you thought you already knew what sex was, what gender was, and all of the essentials about human sexuality. And perhaps so. But in this book I start at the beginning with developing embryos and explore what we know about sex and gender and how well we know it. Then, based on the knowledge gained, maybe we can look at the future of gender, if not definitively, perhaps and at least, intelligently.
