The world’s top chess federation has ruled that transgender women cannot compete in its official events for females until an assessment of gender change is made by its officials.
Why not set up divisions, among sports where the physiological differences do matter, based on the actual weight, strength etc of the individual participants, whatever traits are relevant to that sport, rather than by gender? Even if the average woman and the average man have, say, a strength difference, there are still going to be some women who are evenly matched with some subset of men, after all. I feel like such a system, if done well, could make things more competitive than simply sorting by gender, because it enables sports where the people who are not on the stronger end of what their gender is capable of to still face equivalent opponents, and would remove the whole reason for debate regarding trans athletes, because they could get put into the same categories as anyone else without their identity being invalidated or having any relevance to their performance.
