That's certainly one angle........but it could also be that they understand a need for a certain level of diplomacy and practical, realistic politics in order to achieve their goals. The ideologues/ideologically pure can continue to occupy opposite ends of the spectrum as ideologues always do - but practical achievements sometimes necessitate certain types of compromise.
If the end goal is protecting the dignity, privacy and reality of women and girls in law, then revealing to people the nature of transgenderism furthers this cause. It is always helpful, I find, to listen to the stories of transitioners and detransitioners - to understand their thoughts and processes at different stages - because it reveals what transgenderism is made of.
Yes, we can certainly all feel angry for Stephanie and put ourself in her shoes; and we can see that how much Hayton's process and self definition have dominated the marriage and the lives of their children - but then so will the readers of the article.
I also certainly agree it is not right to impose one's fetishes on schoolchildren: we can all agree on that - and the end goal is to roll back from this madness; but I think we also have to accept it is going to be a long haul; it is going to take at least a coupe of decades to fully unravel.
At some point this crazy trend/ideology will diminish in strength and effect, though there will always be people who identify as the opposite sex, for whatever reason. Cross dressers are clearly large in number and have always been with us - but the elevation of this practice to the status of an imposed totalitarianism to which we must all bow down - will diminish.
