"...to ask them if their child has permission to be in the proximity of a trans person when they're sleeping."
The most generous way to interpret these comments is that the person making them has lost touch with reality and requires significant professional support.
Otherwise, it certainly has the appearance of deliberate disinformation. Anybody with an ounce of common sense knows that what actually happened was that appropriate safeguarding actions were followed when a male child requested to sleep among female children (or vice versa). Of course parents had to be involved if that was in contemplation.
Being trans or not has nothing to do with it. Why has such blatant nonsense and disinformation been given so much power to override basic safeguarding up until the judgment.
Do people genuinely hear this twaddle and think it's about the person being trans rather than about mixed sex accommodation?
