Unfortunately a lot of people who know absolutely bollocks all about child development have pushed the trans agenda to the point where now there is definitely a social contagion going on in schools (partly clearly evidenced by the fact that it is overwhelmingly teenage girls who are wanting to transition).
These people, such as Mermaids, went into schools and told children that if they identify with Barbie they have a girls gender identity and if they identify with GI Joe they have a boys gender identity. They also gave schools advice to teachers including telling teachers that if a child tells them they are trans they should tell the child that they will keep that information secret for them - a safeguarding red flag.
I think we are now seeing the backlash against all this and, as these things so often do, it's going to the other extreme.
I think Bannerman is right about female spaces and the twisting of the EA to gaslight schools and the females within them into thinking they have to accept males into their spaces. I don't agree that schools should just tell kids that their pronouns are horseshit and their identities are not valid. These children have grown up with this crap, we can't just abandon them now. Suella Bannerman is another who probably knows nothing about kids.
I do think that we need to start working on undoing some of the damage that the likes of Mermaids has done with regards to gender stereotypes, start hammering it home to girls that being a female doesn't mean they have to act like a Kardashian, that they can identify however they like but no one can actually change sex and that they are perfect the way they are, no cross sex hormones or mastectomies required.
