On @RoyalCorgi 's point.
Ditum doesn't need to make a claim like that. Once the lid is off, people can make case-by-case judgements themselves.
And she is wise not to. Transitioning autistic teenager girls would be offered as proof the claim is untrue. As ever, malefactors would use the genuinely vulnerable as their shields and attempt to hide among them. So a claim like that would be jumped on to ignore and discredit the rest of the article.
I think it's very well written. Also, highlighting the technique enables us to see when it is used by other groups as well.
