I've got two daughters who will have to make their way in this skinny-obsessed world, and it worries me, because I don't want them to be empty-headed, self-obsessed, emaciated clones; I'd rather they were independent, interesting, idealistic, kind, opinionated, original, funny – a thousand things, before 'thin'. And frankly, I'd rather they didn't give a gust of stinking chihuahua flatulence whether the woman standing next to them has fleshier knees than they do. Let my girls be Hermiones, rather than Pansy Parkinsons. Let them never be Stupid Girls.
