Which is why, again, my point was what would the parents use for justification.
If this is going to court presumably that question is going to be asked. Why do you think your child is the opposite sex?
As I said, I'd be interested to hear whether or not they use gender stereotyping and cod science in the light of DfE teaching guidance forbidding it.
The presentation of gender identity and transgenderism as a civil rights issue is a tactic. One which is immediately abandoned, when calling it a medical condition is more effective.
It constantly switches depending on which argument is being used.
In my opinion, it needs to be firmly rooted in a medical diagnosis of gender dysphoria. Which does not require the people around the individual in question to accommodate it.
If gender dysphoria is a result of the parents believing that stereotypes are innate, than I'd like to see that spoken about publicly, in court. Likewise the born in the wrong body claptrap.
The DfE appear to have grasped the issues with teaching things like the gender spectrum beloved of mermaids. Plus they know there is no evidence of being born in the wrong body. The definitions of what constitutes gender identity and transgender are getting tighter and tighter.
Cases like this will help clarify what they can and can't be. And, ultimately, I can't see the general public being expected to collude in a delusion.
