Gender neutral pronouns are a necessity that we have too long ignored. My understanding is that most languages have these. I can't tell you how fucking sick and tired I am of writing "he or she" in legal documents.
You may refer to me as "the entity known as Icequeen" in your will.
I agree we need something neutral, just not 6-10 somethings. I have enough problems remembering a persons first and last name, let alone whether they prefer Mr., Miss, Mrs, Ms, Ze, or Hir.
