Apart from our names, pronouns are how we identify ourselves. It is how someone addresses you in conversation. There are numerous types of pronouns. They are linguistic devices used to refer to people, such as they/them/theirs, she/her/hers, he/him/his, or even zie/zir/zirs. A persons pronouns tell us how to address and honour them.
Our most commonly used pronouns (he/she) in English specifically refer to a person's sex. These pronouns may not be appropriate for queer, gender nonconforming, non-binary, and transgender people, causing discomfort and stress.
If you are still doubtful as to why this would upset someone, Consider your pronoun (it's most likely "he" or "she"). Imagine someone addressing you as the person you do not consider yourself to be. Imagine them doing it again and again, even after you've corrected them.
A gender neutral or gender inclusive pronoun is one that does not assign a gender to the person being mentioned. The English language lacks a gender neutral or third gender pronoun, which has been criticised because many writers, speakers, and others use "he/his" when referring to a generic individual in the third person. Furthermore, the duality of "he and she" in English does not allow for other gender identities, which frustrates the transgender and gender queer communities.
Gender identity refers to our internal, personal experience of gender. It is directly tied to our sense of self and whether we are male, female, both, or neither. While pronouns are important to an individual's gender identity and how they relate to the world and others, it is important to remember that a person's pronouns are not exclusively linked to gender and may not correspond to your perception of that individual. Your assumption may make someone feel invalidated and dismissed. Investing time in getting to know someone will make everyone feel more connected and respected.
Some tips to to be more gender inclusive:
When introducing yourself, use your pronouns. "My name is Patrick, and I use they/them pronouns," for example.
Include your pronouns in your email signature, event name tags, zoom name, and social media bio.
When addressing groups of people or individuals whose pronouns have not been shared with you, use gender neutral language such as "siblings," "students," "all," or "folks" instead of "brothers and sisters," "guys," "sir," etc...
