My DD is 7 and what I can only describe as a VERY young 7 due to missing so much school over the last couple of years. She came home today and told me she learned about 'men who love men' - fine - and "men who become girls". 
Men can become girls?
Yeah? The teacher said we can just get surgery when we're older. So I can be a boy if I want to. They just told us to talk to our parents. Can I be a boy?
Why do you need to be a boy? I thought you were a tomboy? Why wouldn't you want to be a girl? Girls can do whatever boys can do etc etc.
On and on, back and forth (I'm sure some posters will recognise this).
I went through it with her older sister when she came home aged 10 and attempted to "educate" me. She knows what is what now, but that was a week of non-stop discussion I had no idea was happening until it happened. She thought sex and gender were interchangeable. She thought it was "a feeling". She could not understand why women needed their own spaces and it took telling her about my own experiences (which I didn't really want to do) to convince her.
But... seven? SEVEN?
What adult in their right mind tells a seven year old they can have their genitals removed when they grow up? (Did they mention how many of these surgeries are actually done successfully, I wonder? Highly doubt it!)
I really want to ask if this is actually what happened and this was actually what she was told. Can I? Should I? I realise that would out me as a TERF, but at this stage I honestly don't care? I genuinely believe if she HAS to have this education then there are age appropriate ways to give it which doesn't involve seven year olds being told they can chop off their genitals (or have ones stitched on?!) when they grow up -- they just need to ask mummy and daddy first.
Or am I completely overreacting and this is just the way they're being educated these days? 
We are in Scotland where apparently the government believes 4 year olds should have their pronouns respected... so I don't even know if this was the teacher either majorly fucking up, or furthering her own agenda, or if this is actually the curriculum these days?
I'm just seriously annoyed that yet again there was no warning and it's putting ideas into young heads that A) they can't even understand and B) really does not matter. It feels like they're being indoctrinated into a religion I don't believe in and (certainly in my eldest's case) being taught that non-believers are wrong and going to hell.
She's always been a bit of a 'tomboy'... into football, all her friends are boys, paw patrol for years and hasn't ever looked twice at a barbie. But even at five, she was the one trying to explain to her ten year old sister who came home full of the gender nonsense that "girls can like boy stuff - it doesn't make them boys!!" and now, one sex education lesson later, she thinks she's a bloody boy. And she can just get surgery when she's older to make her a boy 'for real' 😧.
Does anyone have some practical advice on what I can do?
