I disagree. It was part of a bigger answer to this question:
"I welcome the important interim report from Dr Hilary Cass in which she highlights the need for more research into why so many young girls are presenting with gender distress. Will my right hon. Friend agree to meet me and other concerned colleagues to discuss how we can constructively support those young people who are experiencing gender distress?"
He said:
"I would be very happy to meet my hon. Friend. This is one of those issues that the whole House is coming to realise requires extreme sensitivity, tact, love and care. We must recognise that when people want to make a transition in their lives, they should be treated with the maximum possible generosity and respect. We have systems in this country that allow that and have done for a long time, and we should be very proud of that, but I want to say in addition that I think, when it comes to distinguishing between a man and a woman, the basic facts of biology remain overwhelmingly important."
This indicates that the Cass Review is being taken seriously at the highest level. His point may have been incidental or tangential - but his words about the Cass Review are very important.
He chose to mention the significance of biology as part of that question. I note we've heard NOTHING from Stonewall, Mermaids, Gendered Intelligence, LGBT Foundation about his words.
Where's the faux outrage? Maybe they realise the game is up.
So I disagree that this isn't important or significant. It is.
