This week's buzz topic has been masculinity. Adolescence, the extraordinary four-part drama on Netflix, is a frighteningly believable story of a teenage boy driven to extreme violence, writes Alexandra Shulman. Meanwhile, Sir Gareth Southgate focused on the worrying lack of positive male role models for boys in this year's Richard Dimbleby Lecture. If you want to be a man, Sir Gareth said, get into the gym instead of listening to toxic influencers. Girls are steaming ahead in education and, increasingly, in employment. It's fantastic that more women are being given big leadership jobs - for example, Kirsty Coventry beat Sebastian Coe to become the first woman to lead the International Olympics Committee. But it's not so fantastic that positive discrimination means many roles are now handed to women over men when there are two equally qualified candidates.
