In an earth-shattering, mind-blowing, narrative-destroying new scientific study from PhDs at King's College, London, researchers found:
"...a sex gap in race times between athletes who identify as non-binary, and that there is no evidence that the gap between biological males and biological females is less for athletes who identify as non-binary."
In other words - saying you're a girl does not change the fact that you biologically a boy... and that's science.
