Both argue for the the opposite approach that fails to understand that children are individuals, may have reached this point differently and may need different treatments to find acceptance in themselves. Stonewall also seem to misunderstand that adults, teachers and child psychologists are there to help guide children to what is best for the child
I agree. But it's not the schools job to diagnose children. It's the schools job to uphold equality law that should be applied to all children. Gay, lesbian, bi, transsexual and straight.
They have to juggle the protected characteristics of sexual orientation, gender reassignment and sex. To make sure they are being fair to everybody.
The equality law says you should use the correct pronouns and the correct name. After that, it's a question of fairness and balance.
A school can't decide whether a child is merely gender nonconforming, confused, or trans.
It's not their job.
It is their job to take into account all their children, on a practical, day-to-day level. In issues such as toilets, changing rooms and sport.
The guidance they need to adhere to is equality law and safeguarding.
