Rather the OP should thank the adults in the school for deciding to force his girl to change beside a boy just because that boy said "I want to do that"
Awful though it is, there will be people in that school who genuinely think exactly this. Maybe most, if not all of them.
That the school promoting inclusion, being kind, being 'progressive', are all things you should be bloody grateful for.
The detriment to the girls, and the fact that is they who are being sacrificed, is fucking nowhere. Doesn't even crop up. Why would it? That's their job. Dur.
i'm copying this from another thread, even though it's about women in sport, the attitude is identical.
As one leading male sports journalist argued, in a 2019 column for The Independent: “Let’s say transgender athletes pour into women’s sport, and let’s say, despite the flimsy and poorly understood relationship between testosterone and elite performance, they dominate everything they touch. They sweep up Grand Slam tennis titles and cycling world championships. They monopolise the Olympics. They fill our football and cricket and netball teams. Why would that be bad? …In a way, it would be inspiring.”
Exercising the most violent misogyny inspires this nasty fucker. And he's happy to write about it in a national newspaper. Paid for it, in fact
