My advice is to stay prepared, and just stay out of the way.
“Maybe I’m getting cranky as I age, but I honestly DGAF anymore about freaks who engage in self-destructive behavior”
I understand and agree, in spirit. But the initial errant obsession is real, in a child at some age; more than a fantasy.
The professional errors began with professionals taking sympathy to the eztreme and not having enough wise strong compassion - with sympathy - to powerfully help the kid out of the obsession. Those errors fed into parents who also did not want to engage in the log slog of working to defeat the kids obsession. Giving in is easier, emotionally.
But to me the whole thing is like satisifing the problem of an addict by helping them get the means to stay in and live with their addiction.
And to your point, a far great number that do go “trans” continue to have deep related mental problems because going trans does not really and truly resolve the identity dysphoria it all started with - it really remains an argumentno matter how outwardly “satisfied” someone seems.
Mad internal conflict produces all sorts of anger driven outward.
