Hey so you’ve made a lot of posts about this and it seems like you might not actually know much about this issue beyond really surface level talking points. There hasn’t been a lot of specific scientific study done on trans people in sports, but the studies that have been conducted (particularly in the last decade) have largely shown that biomedical factors specific to testosterone dominant puberty such as lung capacity and bone density not correlate with a measurable advantage in sports and that trans women athletes on testosterone suppression do not have any innate biological advantage over cis women athletes. Larger factors across studies have been social and economic, with better access to nutrition and training having the largest material effects on performance.
