The link up thread is daft. They are showing two sets of criteria
- one for gender nonconformity and the other transgender.
Both sets of criteria include the, (surely debunked), concept of playing with opposite sex toys, clothes, peer groups, etc.
The only material difference between the two sets of criteria is the distress felt by the child in question, and the difference between saying they are the opposite sex and they want to be like the opposite sex.
The first being trans, the second being GNC.
If a child says they are the opposite sex, it's just wrong to agree with them.
Sex is a description of biological function. That's it.
Whatever it is they are thinking, or feeling, it is not, quite demonstrably, being the opposite sex.
Interestingly, the older transsexuals we have on here say that therapy included getting them to acknowledge quite definitely, that they understand they cannot change biological sex. That they are still, and always will be, male.
It has to be understood, otherwise there is going to be a lifetime of pain. You cannot convince everyone you meet. It's impossible.
A child who is convinced they are the opposite sex, has either a mental problem, or a biological blip. Either way, they have not, and cannot, change sex.
It is an issue that should remain firmly within the confines of medicine.
