Exactly! That's something that's decided in kindergarten when your woke teacher tells you what you are going to be, right after the drag queen story hour! They have a special deck of cards with all the imaginary genders on them that they pass out to the children, assigning the gender - even some blank cards, so the teacher will tell the student "If your card is blank, then you get to not only pick your gender, but also your species! See me after class for an attachable animal tail!"
