Giving authorities a list of queers is dangerous. Even if the present government is nice enough to include you in some way, ten years down the line you can find yourself with a fascist in power and your name on a list.
I recognise that increased visibility and an increased language for people to engage any identity is likely to make a community more broadly accepted.
But broad acceptance seems like it will never be broad enough for queers in a top-down society.
Already I avoid giving my information to the authorities in any case. They have some, they can keep my gender assigned at birth.
For enbies that are on HRT or have had other dramatic body changes, I can imagine that it might help in some situations to have a different letter in the gender box of your ID. Like travelling? But I’m not sure how this works when, say, your state allows you to have a third gender option but your passport still gives no fucks about it. It might be then that having an ID different to your passport actually brings trouble. I don’t know.
