Most women know this white hot rage. Many are the times I've got off a bus in Delhi, a jagged anger zigzagging through me, because men had groped and molested me, or when a peer had mocked my appearance or silenced me with 'Oh, you feminists'. I've heard it in the voices of my younger colleagues, as they talk about how relatives minimise and dismiss their choices.

So, when I started watching a video of a group of young women berating an older woman for saying they deserved to be raped for wearing short dresses, I knew too well the rage they felt. And yet, I felt myself back away, as the video pivoted, and they sounded less angry, more domineering with utterances such as, "I will make your life hell", "I will make you viral". That familiar, insistent rhythm of social media, of television news outrage grew; the denuding eye of the sting operation grew narrower. The video went viral; the mob humiliated and abused the woman. She apologised.
