How do you protect your children from getting sucked into and brainwashed by this?

As they hit the teenage years, remind them that you know they're growing up and becoming independent and that your job as a parent is to enable that but to keep them safe. They'll make mistakes and you'll support them and help them get through it. Keep talking and (as far as is possible) make sure they're involved in family life, hobbies, one to one with you - anything that keeps them away from the creepy ones on the internet.

Teach them a scathing sense of humour. The most well-used phrase in my house is 'What the fuck is this nonsense now??!' Then we either all have a good laugh at the ridiculousness of the world or totally disagree with each other but proclaim 'What the fuck is this nonsense now??!' at the person we disagree with. So then the person has to explain their viewpoint.

I think they have so much crap fed to them at school and through social media that they have developed a very healthy scepticism about it all without my intervention and pressing them to defend their thinking actually makes them think a bit deeper rather than just accept the nonsense doing the rounds.

I think being very clear that gender stereotyping is rubbish will segue naturally into scepticism about gender ideology when they are older.

Why would someone feel they are the wrong sex if either sex can dress and act however they want.

I also suspect there is a fashion element to gender ideology for a lot of teens - though I’m sure they would deny it - and something else will be in fashion in 10 years’ time. Each generation comes up with its own way to be unique and misunderstood (but in the same way as all their friends 😂)

Ban all forms of social media. All of it. My teens know exactly why we don't allow SM and are fine with it. We answer questions honestly and openly and encourage open discussion. As a result they are very clear that you cannot change your sex 😊

Now that they are very young you can easily and need to control their access to the internet. Keep them off it. Tumblr was famously the place where young people found and got immersed in this ideology and this led to chatting with adult strangers who encourage them for their own reasons ( which I cannot name here)

I was a dress-wearing little girl with curls who climbed trees, played with toy trains and dreamed of being a pirate My conservative parents let me be. I grew up to be a happy lesbian who wears makeup , elegant clothes and studied the law

Mine have always been allowed to wear what they like, like what they like etc. So they had trains, dolls, cars, tea set, toy iron etc etc. They wore whatever clothes they liked regardless of colour.

DS1 is 18 and loves unicorns. My younger niblings have asked a couple of times why he loves unicorns so much "because they're for girls." A breezy "no they aren't. They are for everyone" or "why are they for girls? They're just animals" seems to work.

Likewise when they told me ds2 couldn't have long hair because "long hair is for girls" I pointed out that couldn't possibly be true, because he is a boy and he has long hair.

Keep them off the Internet, or (at the very least) ensure they aren't secretive about what they're looking at. Give the parental controls a good workout. Be 'that' parent at school.

I've laid a firm foundation of love of science and understanding of natural history / biology. The eldest is also naturally in love with history. So it allows some early discussion around evolution, evidence, and with the older one facts and truth. Sources etc. debate.

I did breastfeed well into toddler years and they remember - I've no idea if this helps but they're well aware of the differences between men and women in that regard.

My eldest (boy) is v into football and it's great to point out that a few years ago he wouldn't have had posters of the womens team in the match of the day mag, and why. He knows it's because of the lionesses, but I could have a basic discussion about sexism. Sport helps to highlight the need for female and male games based on biology.

I've challenged gender stereotypes as much as I can with both growing up.

...you can't? They should be allowed to learn of all viewpoints from pretty much any given topic and should be allowed to come to their own conclusions...

Not agreeing with you wouldn't be 'brainwashing'. And given that you presumably love your kids I can't imagine a difference of opinion would be a problem anyway.

I keep them close - as in even at 12, my eldest will talk to me about anything he's concerned about (or, lets face it, anything that pops into his head at the time)

I've taught them (as has experience) that everyone on the internet is a jerk - and how to keep themselves safe (well, as I can) by never using their real name or revealing info about themselves. To only friend people they know in real life.

We have chats about this sort of thing (and other similarly contentious subjects) where we actually talk back and forth, rather than lecture.

From very young, I supported their likes and dislikes, gave them free choice of clothes etc rather than pushing them towards gendered items exclusively (of course if they chose cars/diggers/mummy's little monster t-shirt that was as fine as fairy wands and glitter)

I think the really important thing is the the first though - maintaining a good relationship with them. Whilst there's no doubt I'm the parent, and I set boundaries, I try to be reasonable, and expect them to be reasonable (as far as a child can) in return, and that seems to be working out OK.

Regular chats. I say you can wear what you want/break gender stereotypes and I will support you etc etc but you can’t change sex. I have to keep reinforcing the message because of indoctrination at school etc. They see through the complete unfairness of men in womens sports etc. My mini terfs in training!

Is it two-headed?
