This has been in my local paper (although no poll this far) as there's two affected schools in the area. The poor reporting makes it pretty incomprehensible, as it is unclear by 'transgender girls' exactly what they mean in the first instance. It seems they mean girls who identify as boys or NB, then moves to the opposite. Completely different issues.
If it can't adequately be explained just what is going on, and the local paper only backs this up with selective supportive 'be kind' quotes from naive pupils who believe people are whoever they say they are, then the reality is never going to be addressed. It may or may not be deliberate, but it is yet more obfuscation that makes it easier to frame anyone raising concerns as a 't**f'.
