Datun, I'm just trying to think of reasons why some people don't seem to have an issue with self Id. Maybe if it came to that, in your examples the letters could be send to anyone identifying as woman or maybe registration forms would separate gender from sex. Sports might end up with other categories based on physical differences rather than sex. Etc. That's why it would be handy to know what other countries are doing about these issues.
No you are finding a way to form a rational argument. And I appreciate it.
Separating gender from sex is good idea. Unfortunately it's relentlessly pounced on as transphobic.
Sport being based on other physical characteristics would also be transphobic. The idea is not to separate out people into categories of likely performance, but into categories of sex, except allowing meant to be absorbed into the category woman. There is zero validation for a sportsman, who is not very good, being put in the men's team. And anyway, he will fail, amongst men.
And we can't look at how this is working in other countries, apart from what people are saying, either anecdotally or in newspaper articles, where they are allowed to talk about biological sex. Because men identifying as women, are recorded as women. In terms of statistics.
Hell, the debate has been shut down here to such an extent, that most people don't even realise this is going on.
In New York City you can be fined $250,000 for misgendering somebody.
How the hell can you talk about the problem of not being able to talk about this, when you can't talk about it!
