You don’t have to; you can transition and change your sex to something else. But that should involve a legal and medical process, not you just saying “I am now a man/woman”.
Ok? So what? I had no say in being a man. A trans person has no say in their gender not matching their physical sex. So what?
So do you think that once someone goes through the procedure to get their documents changed to the gender they identify with, the government should destroy all records that they were assigned male at birth? Because that’s what you seem to imply: that once someone transitions, the only government documentation that exists should identify them as female.
I don’t know how much more you need me to spell it out. It seems perfectly clear.
Let’s say that Trump signs an EO saying the government will only issue passports that match your birth certificate gender, male or female.
This would suck for trans people. They’d have to get a passport with a gender they do not identify with, or forgo getting a passport at all.
The Great State of Pennsylvania decides that all birth certificates will no longer list sex to combat this.
What you seem to expect is for the federal government to throw their hands up and say, “I would have gotten away with it too, if it wasn’t for those meddling libs!”.
What would actually happen is that the federal government wouldn’t issue a passport to anyone with a PA birth certificate that doesn’t list gender, whether they are cis or trans.
Does that answer your question in sufficient detail?
You can’t. You have to get them out of power to make life better for trans people. But you also can’t make life better by playing ridiculous games like this one and expecting them to just give up on persecuting trans people.
