—Louise Perry, The Case Against the Sexual Revolution
At the 2016 summer Olympics Elaine Thompson of Jamaica won gold with a time of 10.71 seconds. In the same games, Usain Bolt, also of Jamaica, won with a time of 9.81 seconds. Although there was less than a second's difference between these two athletes, if men and women had been running in the same event, then Thompson wouldn't even have made it into the final race. In fact, she would have been easily out-run by Jamaican boys competing in the under-seventeen category, just as the United States women's national football team in 2017 were beaten by the Dallas under-fifteen boys' team, composed of boys who had just crossed the crucial puberty line and so had begun to develop the strength and power of adult men. The women's category has traditionally been protected in elite sports because, if it were not protected, there would be no women in elite sports—men would outcompete them every time.
