Wyrd, I am duly chastened. And Willa is correct; I asked for it.
Dicho, I am all in favor of language reform, and I agree that we need to find a substitute for gender-based personal pronouns when referring to a person of unspecified gender. I would be happy with "it" as a substitute for "he" or "him". However, until such usage gains widewpread acceptance, I will continue to resist mixing the singular with the plural in the interest of gender neutrality.
Now I will exit this thread before someone finds another chink in my armor.
