Not long ago, most people thought that expanding athletic opportunities for women and girls was a good thing. Then the gender warriors invaded, claiming that “women and girls” was not a real thing at all, just a label each of us can choose for ourselves. Males and females, they said, were interchangeable and should be able to compete against each other. States are fighting back, and the Supreme Court today gave them a green light.Idaho and West Virginia join 25 other states with laws prohibiting males from competing in female school sports. Males, after all, have a real competitive advantage in many physical activities. In 2023, the American College of Sports Medicine released an “expert consensus statement” concluding: “Biological sex is a determinant of athletic performance. … Significant differences emerge at puberty.” The NCAA and the International Olympic Committee now have participation policies based on biological reality.Even the United Nations gets it. An October 2024 report concluded: “Male athletes have specific attributes considered advantageous in certain sports, such as strength and testosterone levels that are higher than those of the average range for females, even before puberty.” Ignoring that fact results in “the loss of fair opportunity” for females.
