I used ‘it’ for my unborn children until I knew their genders, so... I suspect my view comes from seeing the word used in Bujold and other sci-fi writers stories as the singular gender neutral pronoun. I’d want to be called ‘it’ if I wasn’t okay with my gender now (which I wasn’t for a very long time, so thanks for assuming.) Of course, I also have a NVLD, so my view of these things tends to be unusual.
