That is basically what I was trying to argue.
@Shaul is suggesting that one side is demanding people use specific pronouns, but of their choice. I was countering with the suggestion that the other side is also demanding people use specific pronouns, but based on genitalia and genetics.
You make a good argument for a practical solution for the most current problem; there are certainly folks that suggest adding or adapting words in ways that most find unwieldy. But that wasn't meant to be on the scope of my counter, since the basic argument is based around individual choice.
