In March 2014, Fine lent her support to the campaign Let Books Be Books, which aims to persuade publishers of children's books to stop labelling and promoting books as "for boys" or "for girls". She told UK newspaper "The Guardian": "You'd think this battle would have been won decades ago. But even some seemingly bright and observant adults are buying into it again […] There are girls of all sorts, with all interests, and boys of all sorts with all interests. Just meeting a few children should make that obvious enough. But no, these idiotic notions are spouted so often they become a self-fulfilling societal straitjacket from which all our children suffer".
