The post claims Olympic shooting was mixed-gender until a woman won gold, then segregated—and this specific history checks out. Zhang Shan's gold medal in 1992 was followed by the creation of separate women's shooting events. However, the broader claim about sports divisions being created due to male embarrassment doesn't hold up as a general explanation. The sources show a specific pattern with shooting, but they don't support the idea that women's sports segregation across the board happened because men were uncomfortable losing to women. Early exclusion and segregation in most sports reflected structural gatekeeping and male control of sports institutions rather than reactive embarrassment from competitive losses. The post uses the shooting example to make a wider point about current women's sports debates, but that leap from one sport's history to a sweeping claim about why gender divisions exist everywhere oversimplifies things.
