'If there was anything a teenager in America could count on, , it was that she could stand up and ask a question at a political event without fear that a future president would try to grind her into chum. 18 yr old Lauren Batchelder questioned whether Trump was a ‘‘friend to women’’ -- asking about equal pay & female autonomy. On Twitter, Trump called Batchelder ‘‘arrogant’’ and her manner ‘‘nasty,’’ pointing a torrent of supporters’ violent threats her way. Until that moment, it went without saying that a presidential candidate would not use his platform to vilify an ordinary young woman — a wildly disproportionate unleashing of power against a person with little of her own. But assumptions like these are more traditions than formal rules — boundaries made of sand. They’re norms, imprecise and ambient that exist only as long as there’s a consensus, even unspoken, to preserve them.'
