You are looking at this from a place of privilege. What is unfair is the government pretending to see this person as a man, but not really. This man should be listed as a man who gave birth. Period. Notice how calling a man a mother seems "more reasonable" than saying a father gave birth. These both seem out of the ordinary, yet the option that misgenders the parent is the chosen one.
Biologically speaking mothers give birth. It's commonly understood and having something that implies a contradiction, without context, leads to confusion.
I do not believe that "this is how things are, just go along with it." is a good argument.
Great. That isn't my argument if it was, then I agree it wouldn't be a good one.
My argument is that, if folks feel there's a need to change an aspect of something important like a birth cert, then we shouldn't let one-off legal cases, won or lost, be used as justification for having rules confusingly amended and changed without notice and without establishing standards for the new rules so they can be applied equally and fairly - and we have a process to deal with retro-active and historical issues.
This person may not be able to disregard the status quo (guess who that benefits) at this point. Which is really shitty. I hope that there will be a lot of noise caused by this case and things can change.
I am all for changing the status quo. Please do
not misrepresent my position. I feel the status quo in these cases needs a unified push for a resolution that can be fair and equal for everyone. So there's no misunderstanding, no accidents, no misinformation (I wish a perfect system could exist!).
Rules and precedent should not be modified on a case by case basis because, outside of the unique case, it can be damaging and harmful to others.
