Wait, wait, wait, wait, wait~, not to pull on any transgender here, but it said that doctors couldn't specify if Briton's gender, that's slightly impossible, or in this case, improbable, they must only mean that he was androgynous, and there were no genitals to A-Okay a check. However, he still have the chromosomes of a male, and I do believe doctors have the power to see this. The only way that makes it unfair for only him to get a 'gender unspecified' card is that he was still born very male. The only gender that can pull off being unspecified is hermaphrodites, seeing as it's unsure which gender is more dominant, male or female. Though, we too, still have the technology to figure out where the sperm mutated (was it a Y sperm that started to mutate and X, was it an X that started to mutate a Y). Any who, we still have a gender for those without any sexual genitals, they are either male or female, but they are now classified as a eunuch.
It's hard to live as a 'no gender', you just can't do it, it's like saying 'I don't want to be a human any more, so now I choose to not be human :)'. I don't mean it as an offense, I have friends that are transgender, or even no gender, but it's the cruel hand of fate that life had dealt us, I'm not saying you can't see yourself as no gender, I'm just saying if the world were to legally classify someone, they have to include the gender (because has living human beings, everyone has one). But by all means, live your life as someone who doesn't have a gender, that's perfectly fine :).
Sorry, a lot of 'you's in the end paragraph; I'm not talking to any one specific, and this statement does not refer to anyone but Briton
