Surely what children presenting with issues around gender identities need is not medicalisation, it's the kind of anti-stereotyping message of the women's movement in the past: be yourself, make your own choices, follow your own inclinations, grow up to be the kind of man or the kind of woman you want to be, a pro-social human being, not the way some people say you have to be.
We seem to have gone backwards in what we teach children about what 'being a man' or 'being a woman' means, as if feminism had never happened,
which is probably 'mission accomplished' for the anti-women backlash.
There is nothing unusual, and nothing wrong, with children kicking against the constraints of gender stereotyping which they are still subjected to in 2025.
It's not a mental illness, it's not a medical problem, it's a social problem to be solved by backing off and letting children be children in the first place, not forcing them into having to be 'real boys' or 'girly girls', and defining a child as NB or worse still trans, if they find gender stereotypes restrictive.
