This grammar guy has some concern about changing pronouns. Not about changing personal pronouns to match our changing gender views, although the Chicago Manual of Style now accepts “their” as a singular pronoun for he or she. I think that’s awkward, but it’s not the concern here, so please don’t get sidetracked on gender. We have a much more significant aspect of changing pronoun usage, critically focusing on personal possessive pronouns. Who owns what? How? Why? What about my F150 pickup?
