Abigail Shrier, a writer for the Wall Street Journal, has dug deep into the trans epidemic, talking to the girls, their agonized parents, and the counselors and doctors who enable gender transitions, as well as to “detransitioners”—young women who bitterly regret what they have done to themselves. Coming out as transgender immediately boosts these girls’ social status, but once they take the first steps of transition, it is not easy to walk back. Abigail will offer urgently needed advice about how parents can protect their daughters.
