I have long thought that English should have singular gender neutral pronouns. A lot of times you don't know the gender when you are talking about someone, and calling that person "he" by default is sexist. It also is a bit strange that English pronouns are gender-neutral when they are plural but not singular. But I guess I just assumed when English finally got gender-neutral singular pronouns they would be completely new words,1 not the traditionally plural pronounces repurposed to be used in the singular.

1- In college I was a proponent of the gender-neutral singular pronoun "shit," which is a contraction of "she," "he," and "it." Never mind the implicit insult to whoever chose to adopt a neutral gender.
