Any reasonable parent would have concerns about an impregnation-capable boy claiming to be lesbian and sharing overnight accommodation with girls.
Not to mention
a) the fact that parents are not to be told about this or allowed to make an informed choice for their child, and
b) this is totally contrary to the safeguarding rules for any other biological male. As if gender choices remove biology.
and
c) The NSPCC have the 'pants' rule for children, which goes on about 'your body is your own', 'if you feel uncomfortable you have the right to say no' and no one gets to see your body - while also simultaneously holding the position that a teenaged girl, saying no she does not want to get undress and shower alongside a fully intact teenaged male bodied transgirl because she's uncomfortable is to be reminded that she is expected to be inclusive and kind. And the NSPCC say they can't see the whopping great glaring problem staring them in the face with this.
That is what they ran away from facing on MN. That was the question they didn't dare answer. And that was the day I stopped donating to them because that's utterly indefensible.
