I have had to become "that parent" at my DD's primary school. She is 6.
They have been using posters and resources that misrepresent the Equality Act, removing sex as a protected characteristic. The school argued back, including an email from the external provider (No Outsiders), stating that it it easier to teach gender to young children, rather than biological sex, and that one reason for this is is makes gender reassignment easier to teach when they are a little older. The author of resources has a known history in Queer Theory.
I've used Department for Education guidelines, the law and some other resources to explain why this is wrong.
The school have removed the posters.
The sting in the tail, is that I've been phoned and emailed by the school, to warn me off, and threated the police, if I defame the school.
As I had posted a short summary of my concerns on the year group WhatsApp group, when the school hadn't replied to my concerns.
Apparently, parents shouldn't be discussing things that concern them about the school on "social media". They are counting WhatsApp messages as social media.
I have two long long running threads in FWR, and have also set up a resource thread for parents who are concerned about the resources being used in their children's school.
