Reading the link as I hope people will do you'll see it's a bit more complex than you make it sound.
In my experience of young people struggling with gender identity, in every case it's a current culture-driven coping strategy to deal with all the other issues they have - exoerience of racism, undiagnosed or diagnosed neurodiversity, trauma, general 'not fitting in', mental health difficulties of various types.
More support for children and young people suffering in those ways is welcome. If it has to come in a gender envelope, then in a way I'm sorry about that but it is also the current cultural expression of these issues and meets the children where they are.
