Competing access needs: autists need regularity, ??s ("the category of people who go by it/its") need ... creativity? chaos? uniqueness? Those goals are at direct odds.

(I'm going to presume here that crimew doesn't actually want to be considered an object, because we don't generally respect objects' pronoun choices. So calling them an "it" in the grammatical way would be paradoxically self-defeating; we call objects he/she all the time and they usually don't complain.)

This is also why I will always defend the use of "they" as valid. There has to be at least one universal pronoun.
