But although the voices of women must be heard above all else, men must speak out too. It’s really important that we show solidarity with women, educate each other and challenge prejudice in our ranks. In the US and Australia there are more flourishing movements of men against sexual violence, such as Men Can Stop Rape. But there are similar campaigning groups in Britain such as the White Ribbon Campaign and Respect: they have a crucial role to play, too. There is nothing inevitable about violence against women, here or anywhere. Struggle by courageous women and their allies has already had an impact. But the worst thing we can do is allow our horror at what happened on that Delhi bus to make us complacent. Let the death of Damini inspire everyone – everywhere – to defeat this horror once and for all.
