Ah, a clever wee 'says they're, another for the bingo card, as if I would make a mumsnet account and then invent my profession.
I would never dismiss a personal experience out of hand, so I sont know why you needed to precede that. I believe any person who talks about their child.
I dont work in a primary school, but I do work with that age in out of school care in holidays .
Re the autism, that's also something I have a lot of experience in.
I would never support any child, autistic or otherwise, being punished or talked about publicly for making a mistake. That is outrageous, and despite our differences I'm sorry that your child went through that.
However, the article is very patchy. It appears to go from children who are unable to use the pronouns as the pronouns have changed several times which would be fine (nobody, including the child, has any grounds for complaint with accidental misgenderig). I would also be sympathetic to an autistic child who physically cannot express the change, or for any other reason ie global development cannot handle it. That said, I do think parents who are anti trans can exaggerate. I have worked in a base for autistic teenagers where one in trans. Zero have been unable to use the correct terminology. Children tend to be better st it than others.
The article mentions a child who is unwilling to use the correct gender. Assuming no ASN, i stand behind any sanction of this absolutely. Wilful misgendeeing is a totally different thing.
