Help. School LGBT Policy

[AudTheDeepMinded]

Hello. My children's primary school have released a potential LGBT+ policy and are asking for comment. I'm reading through and so far do not have too much of an issue with it but have reached this:
The school will ensure that trans individuals are able to access the toilet and changing facilities that correspond with their gender identity.
Can anyone help me appropriately word a response to this that respectfully encapsulates my unease at this prospect (it affects staff as well as pupils) and does not make me sound unnecessarily prejudiced. Also, does this mean that a transwoman teacher would be able to supervise female pupils changing? Bluntly, this opens up all sorts of possibilities for unscrupulous individuals to take advantage of such a policy. Ah, I'm going to end up being labelled a terf aren't I? Help.

IDK if this will help but Sex Matters has produced an inclusion guide;

''“It should be made clear to all in the school community that everyone is welcome and included – but it is not “transphobic” to recognise that everyone has a sex. This is crucial for equality, safeguarding and sex and relationship education”.''

Thank you for all the constructive advice. I have drafted a letter with some feedback and a (long) list of questions. I'm hoping that these will make those in charge stop and actually think about the implications of what they are proposing and how feasible/legal these will be in practice.
