"Harry Potter" author Rowling has been absent from social media for several days, after erroneously calling female Olympic boxer Khelif a "man."

Author J.K. Rowling has fallen silent on her usually busy X (formerly Twitter) feed, after Olympic gold medalist boxer Imane Khelif filed a legal complaint in France for alleged cyber harassment over statements regarding her gender.

On August 9, lawyers for Khelif filed a lawsuit with a special unit of the public prosecutor’s office in Paris, stemming from false statements that spread online about her gender after the Algerian boxer defeated Italy’s Angela Carini in her first fight of the 2024 Olympic Games. Carini pulled out 46 seconds into the bout and told reporters afterwards that she had “never felt a punch like this.”

    An breakdown of your wannabe argument would be:

    A: “Testosterone enhances performance” B: “Men are in most cases stronger than women” C: “A man punching a woman is unsafe”

    This vaudeville of ideas have no apparent link between them, the real product of a scattered mind. Scientists are still out about A.

    B is a statistical truism at this point irrelevant to the topic, since Khelif is a cisgender woman, and there is no evidence (for the time being) that she is intersex.

    C is also immaterial to the discussion. Perhaps you are trying to say that high-testosterone women are “comparable” to men in combat sports, because they pose a greater threat to cisgender women but this is quite the leap, since she is no man.

    Testosterone levels vary between individuals. Taking part in combat sports entails a risk of serious injury. The weight categories are in place to make things comparable between opponents, testosterone levels are not. Scientists have questioned whether testosterone level correlate that much to performance outcomes as people think.

    The ersatz argument makes no sense.

        I think so, yes.

        Quoting from Transgender Woman Athletes and Elite Sport

        The biomedical perspective views the physiology of trans women’s bodies as the source of perceived unfairness, with medicalized interventions (such as estrogen supplementation and testosterone suppression) as the resolution. More specifically, this perspective holds that sexual dimorphism between those assigned male at birth (AMAB) and those assigned female at birth (AFAB) is the reason for athletic differences. Testosterone measures and boundaries are typically chosen as defining characteristics of manhood and womanhood in the context of sport and are used as the predominant marker to predict and level sex-related athletic advantage and the means for inclusion criteria. The research findings in the biomedical area are inconclusive. Studies which make conclusions on pre- and post-hormone replacement therapy (HRT) advantage held by trans women athletes have used either cis men or sedentary trans women as proxies for elite trans women athletes. These group references are not only inappropriate for the context but produce conclusions that cannot be applied to elite trans women athletes. Further, there is little scientific understanding about the attributes or properties of HRT, namely testosterone suppression and estrogen supplementation, on the physiology and athletic ability of trans women athletes. This ignores the potential for estrogen supplementation to reduce Lean Body Mass (LBM), and for testosterone suppression to produce holistic health disadvantages.

        Quoting from Sport and Transgender People: A Systematic Review of the Literature Relating to Sport Participation and Competitive Sport Policies

        Currently, there is no direct or consistent research suggesting transgender female individuals (or male individuals) have an athletic advantage at any stage of their transition (e.g. cross-sex hormones, gender-confirming surgery) and, therefore, competitive sport policies that place restrictions on transgender people need to be considered and potentially revised.

        Quoting Scientific American Trans Girls Belong on Girls’ Sports Teams my emphasis

        The notion of transgender girls having an unfair advantage comes from the idea that testosterone causes physical changes such as an increase in muscle mass. But transgender girls are not the only girls with high testosterone levels. An estimated 10 percent of women have polycystic ovarian syndrome, which results in elevated testosterone levels. They are not banned from female sports. Transgender girls on puberty blockers, on the other hand, have negligible testosterone levels. Yet these state bills would force them to play with the boys. Plus, the athletic advantage conferred by testosterone is equivocal. As Katrina Karkazis, a senior visiting fellow and expert on testosterone and bioethics at Yale University explains, “Studies of testosterone levels in athletes do not show any clear, consistent relationship between testosterone and athletic performance. Sometimes testosterone is associated with better performance, but other studies show weak links or no links. And yet others show testosterone is associated with worse performance.” The bills’ premises lack scientific validity.

        Quoting from UK-transphobe-funded Strength, Power, and Aerobic Capacity of Transgender Athletes my emphasis

        Results: In this cohort of athletes, TW had similar testosterone concentration (TW 0.7±0.5 nmol/L, CW 0.9±0.4 nmol/), higher oestrogen (TW 742.4±801.9 pmol/L, CW 336.0±266.3 pmol/L, p=0.045), higher absolute handgrip strength (TW 40.7±6.8 kg, CW 34.2±3.7 kg, p=0.01), lower forced expiratory volume in 1 s:forced vital capacity ratio (TW 0.83±0.07, CW 0.88±0.04, p=0.04), lower relative jump height (TW 0.7±0.2 cm/kg; CW 1.0±0.2 cm/kg, p<0.001) and lower relative V̇O2max (TW 45.1±13.3 mL/kg/min/, CW 54.1±6.0 mL/kg/min, p<0.001) compared with CW athletes. TM had similar testosterone concentration (TM 20.5±5.8 nmol/L, CM 24.8±12.3 nmol/L), lower absolute hand grip strength (TM 38.8±7.5 kg, CM 45.7±6.9 kg, p=0.03) and lower absolute V̇O2max (TM 3635±644 mL/min, CM 4467±641 mL/min p=0.002) than CM.

        Conclusion: While longitudinal transitioning studies of transgender athletes are urgently needed, these results should caution against precautionary bans and sport eligibility exclusions that are not based on sport-specific (or sport-relevant) research.

        So even those highly motivated to prove trans women are disproportionately advantaged have difficulty tapping it. As for combat sports, don’t forget Joe Rogan as well female MMA athletes ended up apologizing to Fallon Fox for all the transphobic BS they had spewed at the time.

        What was your point again?

            Anecdotal evidence? Marketing scheme? Performance enhancing drug manufacturer snake oil? How does this respond to a score of peer review evidence. People everywhere in the world believe in astrology and crystals as well. So what?

                Sure, I don’t care about individual studies, due to publication bias and statistical error. I care only about reviews and meta analysis where study hacking and design bias are controlled. Some of the studies will show a positive effect of testosterone. This is included in the studies I posted. A consistent result should show invariably in numerous controlled studies. Some nazis also publish studies in shithole journals, reiterating their 4chan self-complementing arguments. The review I cited show that the effects of testosterone are flaky at best. Also, testosterone in trans women is less than cisgender women, so this is also useless as a premise for either trans women or high-testosterone cis women in sports. So it is a flaky premise, that means nothing for the policies under discussion.

                Why do you think administration of testosterone and testosterone inducing drugs is forbidden for professional athletes?

                Lol this has just as merit as “why do you think they don’t take homosexuals in the military”. Um… because it only takes a bunch of prejudiced guys to believe so in order to regulate so, ever since the Old Testament.

                Is the effect comparable across sports? Are the effects meaningful for high-testosterone women and/or trans women in sports? I doubt it, so do most organizations I cited.
