say this, not that!

Masculine-biased language. It is common to default to masculine-biased language such as mankind, manmade, manpower, chairman and congressman, and to default to "he", "him" or "his" as generic pronouns. This androcentric practice marginalizes and renders invisible other genders by reinforcing the idea that masculinity is the default or preferred. It can create mental imagery that excludes women and people of other genders. For instance, if we continue to use the term chairman then we will always create this imagery of a chair as a male or masculine figure. It also discourages other genders from applying for these roles as they may feel these positions are not intended for them.

Binary language. Binary language presumes that only two genders and two sexes exist. Gender and sex exist on a spectrum and cannot be neatly categorized into man and woman, and male and female without rendering entire groups of people invisible.

Unnecessary gender references. Avoid unnecessary gender references when describing roles. For instance, you might be tempted to describe your superior as "bossy" and blame it on her being a woman when the two are unrelated. However, gender references can be helpful when it serves to highlight issues such as inequality. As an example, 

Go genderless. Always default to a gender-neutral option whenever possible. Be conscious about binary language that implies that only two genders or sexes exist.

Embrace diversity. People are diverse. Sex and gender are diverse. Avoid assumptions about a person's gender, sexual orientation, or pronouns.

Avoid stereotypes. Don't create assumptions about a person's character based on a few characteristics.
