forget that. You get two, he/him and she/her. You don't get stuff besides that. Pick one. I'm tired of these special snowflakes thinking they're oppressed while 250 women have just been executed by CIA for not agreeing to jihad. forget these people. If you want to be a guy, fine. If you want to be a girl, fine. But if you want me to use the stupid pronouns you made up? Go forget yourself.
"its not, because something worse happened"
I mean, I'm not about to go and defend snowflake genders but, you can't really use severity as a legitimate "is it or isn't it?" argument. For example, theft is still crime, despite murder being a more severe crime.
Now, the real reason for gender neutral restrooms is because countries/states are passing laws to force people to use restrooms based on their genitalia, rather than their identity. The neutral restrooms are pretty much saying "you can't tell people they can't use these ones".
