Q. PLEASE tell me what you are recommending when people need a gender-neutral singular possessive pronoun. In order to avoid saying “his mind” or “her mind” (or, God forbid, “his/her mind”) people are saying “their mind”—and it blows MY mind—unless, of course, those people could be sure “they” are “of one mind”! If you have a discussion on this issue, I’d be most happy to receive it or be directed to it.
A. I’m afraid your gender-neutral pronoun (at least in the sense you need) does not exist in our lexicon. I agree that the plural pronoun with a singular noun seems inadequate; I would suggest that you recast the sentence altogether or at least make “mind” plural for agreement: their minds. Other writers alternate between using “his” and “her” in such constructions in order to give equal status to each pronoun.
