Should ‘they’ be accepted as a singular pronoun?

At the American Copy Editors Society conference, using “they” as a singular pronoun was a recurring question. One argument for the singular “they” is that it’s a gender-neutral alternative to using “he” generically. But more recently, “they” has been considered as an alternative for “he” and “she” for people who do not identify as male or female or with any gender. When the issue has come up, many have chosen to avoid using pronouns at all. An editor at the conference said, “You end up having to do linguistic somersaults in order to avoid making any choices on pronouns.”
