The Biden–Harris administration’s unlawful attempt to redefine sex as “gender identity” defies the nature of the human person. A new U.S. Department of Education rule took effect on August 1 in twenty-four states. However, courts have enjoined the rule in the twenty-six states that sued the administration. This man-made law elevates psychology over biology, and its defiance of reality could harm many. A house built without load-bearing walls would crumble room by room. Similarly, safety, privacy, and freedom in a school without sex-specific policies will also collapse in stages. The victims of state and local transgender policies have already seen this in bathrooms, locker rooms, classrooms, and athletic competitions.
