If you don't know why my sidebar description says "they/them", allow me to enlighten you. Quite simply I do not identify as either male or female. I embody a spot on the gender spectrum that is neither wholly one nor the other, I identify as genderqueer and as such I ask that people use they/them as pronouns for me when talking about me in the 3rd person.
So instead of saying "That Jocelyn, she's so cool" or "He has a great blog" you would say "That Jocelyn, they're so cool. They have a great blog".
(I get that this can be hard at first, but try to imagine what it would feel like if someone always called you 'he' when you're a girl, or 'she' when you're a boy. When people misgender or mispronoun me it increases my dysphoria and seriously challenges me.) If you want to know more, feel free to ask me!
