To prove that trans-identified males who have not gone through the testostereone-driven aspects of male development during adolescecne because they started "puberty blockers" before they were 12 really do not have any unfair advantage over females in sport, HobbyJogger and others would have to show evidence that
1) Trans-identified males put on "puberty blockers" (and exogenous estrogen too) as pre-teens do not have, nor do they ever develop, a single one of the male-typical physical features that give males as a sex class an unfair advantage over females in sports.
Such as a male-shaped pelvis and the much smaller male Q angle that make males so much better at running and kicking; male muscles which have a greater number of more-densely packed and faster fibers than females have; tendons that can exert and withstnand more force than female tendons; lungs and hearts that are larger, more powerful and function differently to female lungs and hearts; a thicker layer of dura protecting the brain from sports injuries like concusssion ; stronger male-typical microrchitecture of the blood vessels and other strutures of the neck and cervical spine and so on.
2) Trans-identified males put on "puberty blockers" (and exogenous estrogen too) as pre-teens develop all, most or at least some of the pesky aspects of human female biology that girls and women have to contend with that so often are big drawbacks to u in sports.
After all, the reason males outperform females in sports, and by extremely large margins in adolescence and adulthood, isn't just that male humans develop a host of telltale male features in their own bodies. It's also that males - including trans-identified ones - don't have or develop any apsects of human female biology that disadvantage girls and women relative to boys and men.
Such as the different and more likely to be overactive immune function females have due to our extra X chromosome; the distinctive hearts, lungs, airway cells, airway secretions, breathing mechanics that females have due to our genetics that make us have to work harder in aerobic sports; the enormous hormonal fluctuations of the 28-day ovulation-menstruation cycle and their myriad effects; menstruation; menstrual cramps and other kinds of chronic or recurrent pelvic pain stemming from female reproductive organs and processes; menstrual-related anemia; PMS; PMDD; pre-menstrual breast soreness that can make walking painful and running unbearable; pregnancy scares and worries; female methods of contraception that affect health and wellbeing; unwanted and wanted pregnancies; miscarriage; termination; childbirth and chilbirth injuries; pregnancy weight gain; menopause; common "female troubles" like frequent cystitis/UTIs, ovarian cysts, endometriosis, PCOS, fibroids and so on...
3) Trans-identified males did not undergo any aspect of male development in utero and male mini puberty of infancy that would give them an advantage in many sports and sports-related activties starting from the age of T ball and other pee-wee sports.
