Some people who don't identify with male and female genders prefer not to be referred to with gendered pronouns like "she/her" or "he/him". They may prefer instead to be referred to by non-gendered pronouns such as "they/them" or "ze" or some other term. Do you think it is a good idea or bad idea for social media companies to have a field so that users can share their gender identity as part of their public profile, should they want to?
