Can anyone tell me how widely distributed these "Toolkits" are?*
They're everywhere. A search for 'council trans school guidance' brings up 'toolkits' for Brighton, Leeds, Shropshire, East Sussex, Leeds, Denbighshire, Bath, Cornwall, Wrexham and Berkshire just in the first couple of pages.
My LA isn't mentioned, but it uses it. It also has a video on challenging gender stereotypes. I was delighted, until I watched it. What they do is draw one line from "girl" to "boy" and tell everyone that's sex assigned at birth. And then they draw a second below it, also "girl" to "boy", and that's gender identity. And then they talk through stereotypes (boys climb trees, are brave and strong, like lego and sports; girls are gentle and sensitive, easily upset, love dolls and pretty clothes and pink) and tell them to choose where they are on the second line, boy or girl, according to those stereotypes, because that's your gender identity, and you can be a boy inside even if you're assigned girl at birth, and vice versa, based on those stereotypes. If you are extremely gender non-conforming, then you may be trans. This is suggested for KS1. That's 4-7 year olds. They're being taught, despite no medical basis for it, that everyone has an innate gender identity that's nothing to do with biological sex. As a fact, and challenging it is deemed transphobic, and hateful. So the kids don't want to be that awful thing, and they believe what they are taught. It's indoctrinating them into a new secular religion, and they're told it's science.
Go and look at SRE resources for your local LA. Watch the videos and read the resources. Check to see if they are talking about sex (which means boys and girls defined by biology - personality is wholly individual) or gender (a bunch of stereotypes, which could mean a child thinks they were born in the wrong body... and check out what puberty blockers, hormones and surgeries could mean for that child, if they take it that far... and how many children being treated now are autistic, or anorexic, or have complex traumas).
SRE is now compulsory. You can't remove your children from it from this September. And more than half the resources on my own council's site are about transgender - barely any on race, or sexuality. Very little on disability and bullying. Nothing on girls and sexism at all.
I am donating to this crowdfunder. And talking to my child's school. We are entitled to see the lesson plans, and entitled to question why our children are being taught something utterly evidence free, that has enormous safeguarding implications, without our knowledge or consent, as with the head of Safe Schools Alliance makes plan. Don't even get me started on what happens to children who decide they are trans, and want medical intervention, because that's a whole other can of worms (suffice it to say dozens of medics have whistleblown, are still doing so, and another judicial review us underway).
Of course trans people deserve to live lives of dignity, in freedom and with respect. All people do. That does not mean our children should be taught as factual things that are, frankly, ridiculous - the thread on "is biological sex really real at all!" should illustrate that ably.
This is why so many Mumsnetters are alarmed. Women's rights are being removed under our noses, and women questioning this are threatened with rape or murder, while politicans and journalists say that those women are the bigots. It's Owellian, and I am really sorry, to the women on Mumsnet who have been arguing this for years, that I was one of the eyerollers who thought you all over the top. You were right. Everything you said is happening, or has happened, and we've sleepwalked into it.
The "hateful, bigoted" A Woman's Place site: womansplaceuk.org/ - I'd love to know where the hatred is, because it looks pretty reasonable to me. And here's a thread that explains a fair bit on what's happening to shut down debate and questioning, and why you don't know this is happening at all.
As JK Rowling put it: this is not a drill.
