I can't vote on this. I've worked various different roles in schools and I know how tough it is. However I'm also the parent of kids who might be described as "gender non conforming" and I do not think they need to be medicalised for what is essentially a reaction to the society around them, mired in stereotypes.
The teacher was out of her depth and handled the situation badly. Her own beliefs should not impede impartial lesson delivery. However the guidance is lacking and schools are allowing quasi religious lobby groups to influence or deliver lesson plans. In that sense she was probably in an extremely difficult position, delivering a high stakes lesson she couldn't understand. Plus right now, kids are becoming increasingly disillusioned with the topic.
Of course she didn't deserve recording and her name getting out there. She should never have been asked to deliver that material full stop.
However it is fully understandable that the kids didn't go through the correct complaints channel. From their POV, the school have allowed this deeply unscientific material in. The management cannot be trusted. Remember what a huge responsibility teaching children actually is. Remember the huge power imbalance.
The actions of these kids has to be understood in the context of 2023. Both institutions of power and popular culture dismisses, threatens, slurs and shames people like them who believe in reality. They understood that this might be their only way of getting heard. Use of social media to bypass power happens all over the world where people are oppressed.
This has nothing to do with attacking women. But OF COURSE women are usually the collateral damage, because they are in all things trans rights activism.... It has strayed so far beyond the original remit of protecting actual transexuals that it is essentially a men's rights movement.
