Those of us with children in secondary schools know that this isn't made up.
And those who wish it were, who desperately want it to be, please pay attention. There are quotes, this is a proper newspaper. It's not made up.
We now have a situation where children who wish to bully other children know that the one way they can do so with impunity is to yell 'transphobia' loud enough. And that if they do so, in many if not most schools, then adults will at best condone their bullying and in the worst case join in with bullying their victim. As happened in this case.
The victim doesn't have to have done anything transphobic or even mentioned 'trans' of course. It's wrong think. Anyone who's ever spent any time around kids knows that sometimes they make stuff up to get each other into trouble. Usually the adults in the room are a bit more concerned with finding out the truth - but since in this one case, truth is absolutely the last thing anyone's interested in, it's a free pass.
And of course, it may well be that genuinely trans students (those students who genuinely don't feel comfortable in their bodies, who feel out of place) who end up being bullied by this as much as any other. It's the absolute opposite of being inclusive.
This is what you get with self ID.
