Sex, Gender, and Newspeak

Looking for work (as I am wont to do), I was taken to a Canadian website and wanted to leave them a message in their Contact form and I faced this:

 The company was Sprypoint in Prince Edward Island. I would loved to have seen this
in French, but I could not find a francophone form on their website.

Even back in the 1960s, science fiction suggested species with more than two sexes. Since then, we have decoupled gender from sex. Gender is grammatical; sex is biological. And even before there were seven billion humans on Terra-1, hermaphrodites happened. Now we call them "intersex." And, now, we all have the right to choose our genders within those sexes. The problem with nine pronouns is that we have no social linguistics to support it.

We learn language by hearing it and repeating it. You heard the tones, rhythms, and accents of your native language before you were born. You did not learn it by reading a grammar and copying out the declensions. Until people start talking like this, there is no way to enforce it. In the second declension, why is the possessive of the second person singular hir and not zir or zer? And who decided this?

I do not know French well enough to help them out with this, but if this were German, I would suggest: er, sie, es;  ger, gie, ges; zer, zie, zes; fer, fie, fes; and so on.

Note, also that they allow a Custom choice: you can make up your own. How you enforce that (or any of this) without a name tag is difficult to imagine. And with name tags some are wearing Magen Davids so as not be mistaken for Aryans. 

I like the clicks of Xhosa and other Bantu languages. "Hi! I am Michael: !e, !im, !is." I can see where that might cause some people to yell back at me, but a quick trip to Human Resources and a million-dollar lawsuit would settle that tout suite.
