Gender neutrality is using language — both colloquially and while making policies — that does not assign pronouns or roles based on gender or sex.
This practice recognizes that gender identity is a spectrum and while many people identify as male or female, others don't fit into these categories.
They might describe themselves as a bit of both, one more than the other or neither.
Those who don't identify as male or female, may choose to identify most commonly as nonbinary. Other popular identifications include agender, genderfluid, genderqueer.
They also traditionally reject "he" and "she" pronouns for "they" or "ze" but can choose more than one.
Using gender neutral terms and the pronouns that people choose for themselves is important because it "respects self-identification."
