// Clare - Yet again you are talking up basic rights, which no-one should want to deny, and ignoring the trumpeting for indulgence that is the root cause of intolerance. //
I'm not ignoring it, I'm saying that its scale is being greatly exaggerated and often used as an excuse to deny the former.
Take toilets as an example. In the example you gave, apparently it was decided that the child shouldn't use toilets matching their birth gender, but neither would the school be comfortable in allowing them into toilets matching their social gender. However, they still need to go to the toilet *somewhere*, no? So the disabled toilet is the only remaining option. I'm not entirely clear why it was decided that a teacher has to accompany them at all times, but perhaps there's more to this story that explains this extra measure being judged as necessary.
Extending this to adults, most facilities provide either individual self-contained toilets and bathrooms, where only one person is around anyhow in which case there's no issue, or provide men's, women's, and disabled loos separately. But it's the same situation: a trans person has to go *somewhere*, and naturally prefer in the first instance to go to the toilet matching their identity. Failing that, they'd go to the toilets that are most likely to avoid leading to any uncomfortable or awkward situations. But this is what "shut[ting] up and get[ting] on with it" entails: going to to place you're least likely to be noticed. If a trans woman walks into the gents' then they'd stick out like a sore thumb and draw exactly the kind of attention neither you nor they would wish. But such a person walking into the ladies' isn't "demanding" anything other than to pee in peace.
At some point, then, it's hard not to wonder if your definition of basic rights extends only as far as trans people remain entirely invisible, exercising their rights in silence and in private. Now, perhaps this is unfair. But selecting the "battlegrounds" of toilets and changing rooms seem to amount to precisely this: it means that trans people, whenever in public, must act in a way that is simultaneously not attention-seeking but also is incongruous with their mode of presentation (which just ends up drawing attention).
