In Joe Biden’s town hall earlier this month, one of the questions came from a woman named Mieke Haeck, a 42-year-old physical therapist from State College, Pa. “I’m the proud mom of two girls, 8 and 10,” Haeck said at the televised event in Philadelphia, while her husband and children watched from their living room. “My youngest daughter is transgender.” She spoke of how the Trump administration has repeatedly rolled back the rights of the transgender community, and asked the presidential candidate what he would do to protect the lives of transgender people like her daughter. “The idea that an 8-year-old child or a 10-year-old child decides … ‘I want to be transgender … it’d make my life a lot easier,’ ” Biden said in his answer. “There should be zero discrimination.” But by the next day, Biden’s answer — and Haeck’s family — had become the subject of political attacks from conservative commentators and social media trolls.
