That said, I'll just say it again: all this DSM and identity stuff and whatnot is really doing a motte and bailey fallacy on what is really demanded.
If the question is just what you want to identify as, then sure, knock yourself up... err... out. Whether it's male, female, other, cat, or even attack helicopter, go for it. I'll be the last person in the world to try to stop you or say there's anything wrong with it. Good for you, Mr Boeing AH-64 Apache.
The problem is more like, well, what seems to be the current fashionable plague of self-styled 'progressive' activism, particularly in the USA (or at least that's the impression I'm getting): expecting that everyone cares deeply and at a personal level about your problem, and puts it above any other problems. And gets it shoved in their face regularly, just so they don't forget. Whether it's about gender or race or being a vegan or even trivial stuff like Windows-vs-Apple, it's not just enough that people let you do whatever you want to do, they have to care deeply and personally about your cause. And if they don't, then verily it's the same as being persecuted.
But that strikes me as not being about rights or anything, it's just being a spoiled brat who never grew up.
The pronouns strike me as a case of just that. It's not just enough that people go "yeah, identify as whatever the fork you wish." Everyone has to remember that you specifically are the one they should refer to as "xi", the other one is "ae", and the other one is "boop". Someone merely not having had your problem shoved in their face often enough to hammer it in, is somehow insulting or bigoted.
Sorry, that's no long about the right to identify as X, it's about the right to shove your problem in everyone's face and demand that they care about it.
And, sorry, to quote Ron Swanson again, "
The less I know about other people’s affairs, the happier I am. I’m not interested in caring about people."
Unlike him, I'm not even some right-wing libertarian. I'm a left wing statist. WAY left wing. If you have a problem, I'll happily pay even more tax so that a government agency deals with it in an efficient and uniform manner. So I don't have to. (And I already pay about half my income in taxes, so I fancy being willing to pay even more is substantial goodwill.)
Or if that's totally not enough, and it's such a terminal case that you absolutely can't live without some impossible condition (like every last one of us deeply and personally caring that you want a lollipop), I might even be willing to buy you a one way ticket to Switzerland out of my own pocket
