It's the shift from a child centred approach to an approach led by an agenda.
Most parents of teens will have adopted "watching waiting" in some form or another. Too much gaming, too much partying, not enough homework, whatever. You advise, steer and maintain reasonable boundaries, but you stop short of absolute confrontation in order to maintain communication, whilst crossing your fingers tightly. If things become serious, you seek help from experts, who you also hope will have the child's welfare absolutely as the priority.
10 years ago this seems to have been happening.
Now....
All sorts of people running their own agendas. We all guess at Susie Green's need for justification. Then there is the "brave and stunning" brigade who need trans-children to justify their claims that they were always in the wrong body. And, quite possibly, others with darker agendas. Then the woke crew: Lloyds, the BBC, Lush, etc who want the image, the brownie points etc for supporting the mutilation of children.
So the approach became more prescriptive, and watchful waiting goes out the door. Unhappy teenage girls being offered hormones within months of announcing their dysphoria. Parents being told "better than a dead child". Medics lobbied on treatment approaches. Teachers and social workers working against parental instincts, with virtually no support for parents who resist.
I hope the Sunday Times have found the key stone in this crap, corrupt edifice and the whole lot comes tumbling down.
