The intentional aim is to confuse and obfusticate language and create social anxiety around it in order to prevent women being able to have the words to express what they mean or to refuse the validation this is all about.
Which is partly why here where possible women tend to use the right terms and not buy into it. As a pp says, the real world knows exactly what the words mean and don't know about this online jargon, it's nonsense to most. witness on women's hour, the effort to try and get TRAs to explain what 'cis' meant (and they couldn't, essentially.)
It's been very interesting watching the Scots census discussion and seeing people realise for themselves, sex and gender have to be separated. You can be any gender you want, great, but sex is a fact and needs to be considered separately. That's the only way forward. Plus, as I keep saying, reminding the authorities over and over again, however supportive you wish to be of people who hold unusual and different beliefs, women may not hold these beliefs. It is reasonable to believe a TW is male. Women holding this belief will not be amenable or even able to tolerate a TW doing anything they would not be ready to agree to any other male doing.
That's very difficult in law and policy to ignore.
