//The first point is that it frames all transgender people, young or otherwise, as potential threats,…//
I don’t think it’s that at all. It’s simply to reinforce the principle that in certain situations and circumstances people are segregated on the basis of biological sex (a fact) and not assumed gender (an opinion). This arrangement suits probably more than 99% of the population. So why should that vast majority have their wishes overridden by such a small minority?
The situation is becoming ludicrous and leads to events such as this:
https://www.lbc.co.uk/news/female-teacher-apologise-good-afternoon-girls-20k-a-year/
A teacher at a girls’ school (the clue is in the name) was forced to apologise to a class of eleven year old girls and eventually “managed out” of her position (by which I imagine she means constructively dismissed) because she greeted her charges with “good afternoon, girls”.
//This stuff is being force fed to our children -//
Indeed it is. Interestingly the protest I mentioned above took place shortly after the sixth form's "diversity and inclusion" prefects did an assembly on gender and pronouns.
Harsh as it may seem, single-sex schools are segregated on the basis of biological sex. A girl is a young female human being. If there are some male human beings in the class, firstly, parents of the other pupils need to question why they are allowed to be there. But if they are, they must either put up with being addressed as a girl (in an all-girls’ school) or their parents must seek education for them elsewhere.
