Genderqueer writer and filmmaker Stuart Getty's How to They/Them: A Visual Guide to Nonbinary Pronouns and the World of Gender Fluidity is a charming, often witty and useful guide to a serious subject.
Aided by cartoon-style illustrations from Brooke Thyng, Getty tackles big questions, using a generous helping of personal anecdotes to make their points. They explain the difference between gender identity and sexual orientation, and how both relate to the question of sex assigned at birth. They outline a range of possible gender identifications beyond the binary he/she. They explain why someone might prefer to use the pronoun "they," and place that usage in both historical and multicultural context--obliterating the argument that it is "not grammatical" in the process.
With the background of who, why and what established, Getty moves on to a wide-ranging discussion of practical questions about using they, both for those who identify as they and those who don't. Much of their advice boils down to being polite and not assuming, recognizing that both may be difficult at first. They also point out structural issues that organizations can address to be more gender inclusive. In what may be the most important section, they tackle the difficult questions of talking to a friend or relative who refuses to use your correct pronouns, as well as talking to kids about pronouns.
Getty begins and ends with the assertion that their book, and the use of they as a singular pronoun, is ultimately about freedom. They make their case. --Pamela Toler, blogging at History in the Margins
