When I first saw that I didn't believe it was real. When it became clear that it IS real, I saw it first as a grotesque parody of what it means to be a woman, and then thought of all the other things mentioned (child safeguarding, occupational safety, lack of proper mental support for the teacher turning into some sort of an impossible misogynistic caricature of womanhood etc.).
But the fact that this is a grotesque caricature of one biological sex does matter to me, a lot, because the way these rules are enforced means that the only rights the rules support are those of a transgender person wishing to do this. The possible negative consequences to others are ignored.
That others might be negatively affected by this is of no importance at all (their concerns are seen as apriori bigoted), so that it is fine to show students this rather novel interpretation of what being a women might mean, even if that interpretation is clearly a misogynistic one.
In reality everyone's rights are supposed to be taken into account. Here only one group's rights matter.
