alternative pronouns to they/them are good and let me tell you why.
english is one of the only languages where they/them can be comfortably adapted to a single person. other languages don’t have this option often.
support people who use pronouns like xey/xem and zhi/zhem. support Jewish people who use the nonbinary genders listed in the Torah. support people who go by pronouns that mean “it” in their languages. support people who make up their own pronouns.
and if you use nontraditional pronouns or pronouns from another language please know your gender and you are valid and beautiful, and your pronouns deserve to be respected.
