Somerset House in London has put on an exhibition on the work of Charles Schulz, the American cartoonist famous for Peanuts – the story of Charlie Brown, his friends and his dog called Snoopy, a beagle with a taste for ice-skating and root beer. The show commences unpromisingly: “This exhibition explores the ways in which Peanuts has touched us all on so many different levels... on issues such as war, racism, feminism and gender-fluidity.” Oy vey. Why does everything nowadays have to be a political seminar?
