It's an interesting idea, but (as with so many surveys) I often want to know what the question actually means before I feel happy answering it.
More generally, on third-person pronouns:
- I try to use each person's own preferred pronouns, where I know their preference. Unfortunately the bit of my brain that does gender recognition seems to be hard-wired to the bit that does language, and they sometimes outflank the bit that wants to be respectful of people
- Using "it" etc. for a person would feel odd to me - for me, those pronouns strongly imply something being inanimate, or at least not human.
- I would very much like for the default third-person pronouns in English to be non-gendered; unfortunately, I think it will be quite a struggle. "They" seems the one with the best chance of acceptance - I can see why people have invented various others, but none of them feel right for me.
