I coached high school sprints and hurdles in Southern California for years. After puberty hits, the difference between male and female athletes shows up in split times, in jump heights, in the raw gap between what each side of the track can produce. That gap is not a social construct. The American College of Sports Medicine confirmed it in peer-reviewed consensus: post-pubescent males outperform females by 10-30 percent in events requiring strength, speed, and power. This week, the Supreme Court agreed.

The Court ruled Tuesday, June 30, 2026, in Little v. Hecox and West Virginia v. B.P.J. that states may bar transgender athletes from girls' and women's sports teams, upholding the Idaho and West Virginia laws and, with them, the similar protections now on the books in more than half the states. It's about time common sense ruled the day.

Justice Brett Kavanaugh wrote the majority opinion. Kavanaugh has spent years coaching his daughters' girls basketball teams, the kind of practitioner experience this debate has needed from the start, someone who has actually stood on a sideline and watched what a mismatched matchup does to a team of 12-year-old girls.

The Court didn't reach for a sweeping equal protection theory to get there. It found the answer in the statute itself: Title IX, the 1972 law barring sex discrimination in federally funded education programs, explicitly permits sex-segregated athletic teams. If Congress built that allowance into the law that created modern women's sports, states are free to define team eligibility by sex at birth. The Court threaded the needle by reading the law as written, not as advocates on either side wished it had been written.

That sentence is not a throwaway. For six years, parents, coaches, and the girls themselves were told that the visible, measurable, repeatedly documented gap between male and female athletic performance was a........
