Teen activists aren’t often met with a pop star’s welcome, but Malala Yousafzai’s arrival can ignite a fever-pitched frenzy worthy of the Selenas and Biebers of the world. That celebrity effect is on display during a recent swing through Lancaster, Pennsylvania. There’s the young woman at the indoor food bazaar, who leaves Malala’s embrace in tears, and the teen refugee who cries so hard she can barely speak. Admirers gather for autographs and photos everywhere Malala goes (a suited security guard and small army of staff trail closely behind). At a local high school, throngs of teens rise and scream when she enters the stage. “I can’t believe I got to ask Malala a question!” one gushes in the hall outside.
