Why does it matter?
In English, our most commonly used pronouns (he/she) specifically refer to a person’s gender. For queer, gender non-conforming, non-binary, and transgender people, these pronouns may not fit, can create discomfort, and can cause stress and anxiety.
A recent study showed that in transgender youth, using correct pronouns and names reduces depression and suicide risks.
Having trouble understanding why this would upset someone? Think about your pronoun (it’s probably “he” or “she”). Now imagine someone calling you the one you don’t think of yourself as. Imagine them doing it over and over and over, even after you’ve corrected them.
