「医者」という主語なり目的語なりを代名詞のheとかhimとかでうけてしまいがちだが、医者が男だと決めてかかっているよ、ということで、性別に関わらないような代名詞を使いましょうという話。タイトルをGender-free Languageにしたが、Gender-Neutral Languageという表記を使うのが一般的だろう。

American Sociological AssociationのQuick Style Guideにもそういう記述があった。
Bias-Free and Gender-Neutral Writing Avoid gender bias and ethnic stereotyping in your writing. Use words such as "person," "people," or "humankind rather than "man," "men, or "mankind."
When you must refer to both sexes in a sentence, use "he or she," "her or him," "his or hers" instead of "helshe," "himlher," "hislhers." Vary the gender order on occasion. Also, of course, you can change your subject to plural;"they" is "genderless. "
