• "How Using 'They' As a Singular Pronoun Can Change the World." - Mostly about the singular 'they' when applied to the individual, but contains solid thoughts about the roles of power and gender in everyday language
• "Gender-neutral language is coming- here's why it matters."
• Wiki entry on discrimination against nonbinary gender identities
  • Look at the sections on Nonbinary erasure and Binarism
• "Dear Sir/Madam: a commentary on non-binary erasure."
• "We Are Non-Binary Trans People, and Yes, We Exist."
• "Breaking the Gender Binary." - less a discussion of the semantic and more an accessible overview of nonbinary identities, discrimination against them, and issues nb people often face
• Gender-variant identities worldwide
  • While not all people who identify as nonbinary claim native identities, it should be stated that nonbinary identities have existed throughout the length of human history, often most notably in indigenous, marginalized, and non-Western cultures. Erasure of these identities is part of the erasure of native peoples and cultures, and contributes to a colonial culture of forced conformity.

A word is a very small thing, but efforts towards inclusion are anything but. The fact of the matter is, when you perpetuate the use of "he or she" in documentation, you are still radically calling to the surface the knife's edge between two polarized points. "Or." He or she. And where am I, who am neither he nor she, who have had to fight every inch of my way to be recognized and validated as a person, supposed to find myself in this documentation? Are you protecting my rights, too, or not? Am I part of the organization? Does my work not benefit the institution, its mission, and its patrons? "He or she" privileges those people who are comfortable with the existing structure of binary gender, erases the discomfort of those who do not, and leaves us no room whatsoever to negotiate for our needs. We are not included. This is the outright definition of maintaining the status quo out of the comfort of the privileged, to the detriment of the oppressed. You will say, perhaps, that there are not that many of us, that our discomfort and erasure when compared to the inconvenience of amending something as "insubstantial" as a few pronouns is just one of those things that we have to deal with in a system as big as ours. But if we aren't given the basics of inclusion, where are we supposed to have conversations about the bigger problems the binarism of the extant structure metes out against us? If we aren't allowed to use the words, how can we argue for ourselves? There are more of us than you can know, because you prefer not to know. But we know. And we feel the system pushing back on us every day, from every direction.

Not being inclusive in our language hurts everyone. By straining with that "or," we keep the comfortable and privileged from recognizing and acknowledging those who are different from them. By demanding that everyone be covered by "he or she" we close the doors to explorations of what might be both, or neither. We shut out people like me, who have never been included in that "he or she," entirely. To you, it might be a small thing. But to me, it's my whole life.
