i'm ok with 'she' offline. it's a kind of automatic thing that happens to people when they see hips and boobs. pointless to defy it, because of defaulting.
but online, i prefer 'he'. for the sake of balance.
if i'm ever called something else, i hope it will be well camouflaged, in words that neither reveal gender, nor state insecurity about it. but that's really difficult to do in languages with gender specific pronouns, and even worse when gender is applied on verbs. like russian past.
i like 'it' as a pronoun. not for me, i'm usually far from it, but whenever sootball is around, both it and me feel more like it.
i also know a person who's perfectly fine with being called it, but that one's a tentacle monster.
it isn't dehumanizing in any way i can think of. it's more like a very ungender kind of think, and that might be the reason why most people don't like it. seems like gender and sexuality are so important to them that it gets difficult to relate to anything that isn't a 'he' or a 'she' or at least 'they'. aren't 'it's human too? or at least proper persons (even grammatically). (reason why i'm rarely it, is that i have too much gender.)
my language frequently uses equivalents of 'it', 'that', and 'this' about people. doesn't sound weird at all. but that might be because the pronoun for a 3rd person singular is unisex.
funniest application of they, is for a person who thinks of themselves as twins. they're really a correct kind of person to call they, don't you think?
