This is honestly getting ridiculous now.
And it's getting into schools too. A couple of years ago we had an organisation come in to do a talk on puberty and sex to Year 7 and the woman delivering it used torturously degendered language to the point where the children were confused. Afterwards, one of my male students, who has autism, asked me when he would get his period, because nowhere in the talk was it made explicit that only girls/women have periods.
It's also hugely problematic for people for whom English is not a first language - information regarding health needs to be clear, precise and free of any ambiguity.
'Women and transmen' and 'Men and transwomen' should be perfectly acceptable to use - they are statements of fact and they are clear and unambiguous in whom they are referring to. However, because of this ridiculous insistence that 'transmen are men' and 'transwomen are women' - despite the fact we all know that, biologically, they're not and never will be - it's become impossible to call a spade a spade without having coals heaped on your head. In circumstances where biologically matters - as in medical literature and health information - we have to prioritise facts and not feelings.
And of course what it all comes down to is that the only people who are at risk of having their health and safety compromised by the erasure of sex-specific vocabulary are women. It is, purely and simply, misogyny. Transpeople have every right to live their lives freely and with the same human rights of every other person on the planet. I don't dispute that. What I don't think they have the right to do is insist that other people's lives, health and safety are placed at risk unnecessarily through insisting that the whole world is pivoted to place them and their feelings at the centre.
