I know this will be hard, because we’ve learned from such a young age that certain names are ‘boy names’ or ‘girl names’, but we should work towards stopping to associate names with gender.
When someone tells you: “Hey, I’m Steven, I’m a girl and use she/her pronouns!” then she is a girl and you’re gonna use she/her pronouns for her. “I like Steven, she is a pretty girl and my best friend.”
When someone tells you: “Hey, I’m Cathy, I’m a boy and use he/him pronouns!” then he is a boy and you’re gonna use he/him pronouns for him. “This is Cathy, he is my boyfriend.”
When someone tells you: “Hey, I’m Peter, I’m agender and use ey/em pronouns!” then ey is agender and you’re going to use ey/em pronouns for em. “Peter is my favourite person because ey is so nice.”
Some trans people want to keep their birth name. That doesn’t mean they are less trans, or that they are less worthy of respect.
