Rather than argue about whether gender identity is valid, it may be more constructive to take it for granted and instead consider the goal of having separate sporting events for men and women. My understanding of the goal is that it gives women a fair chance to win events without competition from (on average) physically stronger men. That is, gender is not important
per se, but rather the fact that half the population is not on a level playing field with the other half. If women were equal to men in physical strength, but brown-haired people were weaker than blonde-haired people, we would instead have sporting events segregated by hair colour.
If we accept, then, that gender is no more than an incidental part of the reason why we have women's sporting events, we can begin to consider what
is significant. I can see a few options:
- Abolish all gender segregation in sport and allow the best athletes, of any sex and gender, to win.
- Establish some standard by which trans people can be medically certified as having transitioned to the point that they are of typical stature for their target sex, and hence permitted to participate in sport for that gender.
- Base segregation in sport on sex at birth, and not gender, while acknowledging that these are now mixed-gender sporting events to accommodate trans people.
- Abolish gender segregation in sport, but establish a tiered system where athletes compete against people of similar physical stature to them, regardless of sex or gender.
The first option would undoubtedly mean that men win most events, which would upset feminists and risk injury to women in contact sports, so it is not ideal. The second is extremely difficult to get right due to the fact that differences between the sexes are only broad averages, so whatever standard is chosen, it will do nothing to settle the controversy.
I therefore posit that the third and fourth options are the only workable ones. That is, we need a reform of gender-segregated sport. The question is whether to base the admission criteria on physical sex, or on some other means of classifying physical strength.
