Sir: The logical conclusion of politically correct dating as set out by Katie Roiphe's feature 'No means no. But what does rape mean?' (21 August) is surely not verbal but written consent - possibly even witnessed. Political correctness is just one of the weapons used by feminists in their battle to 'Take Back the Night'. Unfortunately, if the night they seek to reclaim is emasculated by such nonsensical conventions, will it be worth the candle?
