Mary McAlister
Parental rights attorney
Mary McAlister is an American attorney who has spent years in court defending parents whose children were socially transitioned by schools without their knowledge or consent. For British parents navigating conflicting school policies, post-Cass NHS guidance, and a legal framework still finding its footing, her courtroom experience offers hard-won lessons about what parental authority must mean in practice.
Mary McAlister is an attorney who has specialised in defending parental rights against school policies that socially transition children — changing names, pronouns, and sometimes dress — without informing, let alone consulting, the family. Her cases have taken her into some of the most contested legal territory in the United States, where districts have argued that notifying parents amounts to endangering a child. The parallel in Britain is direct: the same justification has been used to defend practices that the Cass Review ultimately found wanting, and the Department for Education's statutory guidance on sex education and gender questioning pupils has been shaped, in part, by the same argument playing out on both sides of the Atlantic.
In her Beyond Gender episode, The Kinsey Legacy and the Fight for Parental Rights (December 2025), McAlister drew a provocative intellectual line from Alfred Kinsey — the mid-twentieth-century sexologist whose research methods have long attracted serious challenge — to the contemporary frameworks used to exclude parents from decisions about their own children. For British listeners, the Kinsey thread has particular resonance: much of the training material that shaped NHS gender services, school pastoral practice, and social-work guidance over the past two decades drew on the same international tradition Kinsey helped to establish.
McAlister's core legal argument is that schools act in loco parentis, not in opposition to parents, and that parents are the primary decision-makers for their minor children. That principle sits at the heart of the Cass Review's concerns about children being supported in social transitions without family involvement — the very failures that led to the closure of the Tavistock's Gender Identity Development Service in 2023.
Her work is a reminder that Britain is not charting these waters alone. American courts have already produced case law on school notification policies, privacy carve-outs, and the limits of institutional discretion — precedents that British advocacy groups, family lawyers, and policymakers are tracking closely as guidance and legislation continue to develop.
