He's not @'d her but he's tweeted her comment piece in the Telegraph from last week:

Underneath, he's added an archived link and a comment, saying: "It is worth noting that kids who are same-sex attracted and/or autistic are the most vulnerable".
As he's has a lot of followers (140M or so), this means a lot more chance of the issues reaching a lot more people.
Previously this kind of thing would have risked being taken down on Twitter, so it's maybe a sign that #nodebate is gone/going.
