I agree it's a very useful narrative, but it's a bit desperate at this point.
No, I don't believe any legal document should be fictionalised because someone is happier with fiction on it than the truth - that way madness lies.
No, I don't believe that there should be a group of people more special than others, with special freedoms and entitlements under law and higher regard than any other group - that way madness lies.
No, I don't believe that women should be forced to accept subordination and lesser rights to accommodate some men from this special group, including autonomy, privacy and dignity that are basic human rights, or to expect lesser care and respect than that afforded to those men. That way madness lies.
No, I don't believe that safeguarding for children should be adapted based on a special group of people, and the attendant risks handwaved away. That way madness lies.
No, I don't believe reality should be based on the feelings of the most powerful with others forced to comply, instead of the objective perceptions of all. That way madness lies.
These aren't extreme beliefs, you'd have to be beyond uneducated and naive to think enforcing this on a society is going anywhere that ends with sunshine, rainbows and happiness for anyone. The behaviour and reality of this political movement has opened people's eyes to what 'be kind' and 'trans rights' means, and they're seeing through the marketing to the above. They're not likely to be effectively hate crimed and bullied back into compliance at this point, and trying is going to make them steadily angrier and more resistant.
But if that's what it takes to get enough of the populace angry enough to shake Whitehall back to sanity, then whatever.
