But Olympic athletes as as a category are not stronger than other Olympic athletes. Men, as a category, are stronger than women, and there's a plausible case that trans women are, as a category, stronger than cis women. The point is not to eliminate the possibility of any given individual having a biological advantage over any other individual, but to foster a competitive environment, which in practice means relying on category-based generalisations. This is, in itself, uncontroversial; the point of contention is which generalisations about which categories.
