Concept on New Gender Settings, and Why the Pronoun Settings Are Non-Intuitive

I wasn't privy to the original broadcast; but this system you've thought up seems very well thought out, and I doubt most people could find flaw in it.

With regards to the plural possessive on Pronouns like "Zir"/"Zirs", maybe a simple option to toggle the S on the plural form (they do this in programming all the time, but you rarely notice it when you read the localized strings in English)

Edit: Also Let's be reasonable, with all the spinning they do on their parents backs, many Toddlers identify with "Helicopter" :P
