[1] If this issue is so clear cut, then I wonder why like any guidance by medical organizations for transitioning people state clearly “expect muscle and strength loss at the level that it might affect your grocery carrying experience” (like this https://www.wpath.org/publications/soc ). [2] Don’t forget junk science has targeted women of color, intersex women, and even normal women with high testosterone levels https://www.cnn.com/interactive/2021/07/sport/athletics-testosterone-rules-negesa-imali-running-as-equals-dsd-spt-intl-cmd/ for exclusion from female sports. [3] Now to your “academic” points. Your first reference is written by an inarticulate person reciting long debunked gender stereotypes in some third-world journal, without even backing it up. Low quality article all around, appears like a targeted attempt to give academic substance to age-old stereotypes. In contrast Scientific American has published that “trans girls belong to women’s sport” https://www.scientificamerican.com/article/trans-girls-belong-on-girls-sports-teams/ since “there is no scientific case for excluding them” and “a visualization of sex as a spectrum” https://blogs.scientificamerican.com/sa-visual/visualizing-sex-as-a-spectrum/ which I guess debunks all certainties of the said article. [4] Your second reference is a cherry pick from an article that states exactly the opposite “The 15-31% athletic advantage that transwomen displayed over their female counterparts prior to starting gender affirming hormones declined with feminising therapy.” (from the abstract), so what you have written might be just a little bid …dishonest? [5] And the third is a N=1 case study of one champion? It compares a single person before and after hormones to the “established sex differences”? Come on! I could even bring in articles on your side of the argument that could be more hard to debunk. The Karolinska Institute study is one for example http://biorxiv.org/lookup/doi/10.1101/782557, who went to great lengths to skew the sample to make a seemingly neutral contribution. [6] Look for systematic studies, cherry picking is cheating: Here is a systematic review https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5357259/ It is inconclusive whether testosterone drives athletic performance, and studies are inconclusive about trans women having unfair advantages. But they do point out that prejudice stigma and violence is a factor for transgender athletes. If anyone wants to be fair has to factor in the shit trans women will take in male sports, plus that some male athletes may find it unfair to compete them in case they recognize them as women. Also some athletes and commentators have switched sides about their prior strong rhetoric on the matter https://www.thedailybeast.com/mma-fighter-rosi-sexton-apologizes-to-fallon-fox-for-transphobic-comments and I think Joe Rogan himself apologized to.
