I find it so disappointing that out of all the things pronouns could represent somehow we have ended up with gender. We could have pronouns that represent the relationship you have with the person you're talking about or whether they're a cat or dog person (or maybe both or neither?) or something else cool. Instead we get gender, which is a personal and sensitive subject for some people and basically gives people an excuse to try and figure out someone's gender and/or sex, which tbh, isn't any of their business in most situations. It's such a personal thing that has to be made public just so people can talk about you in third person.
