You’re getting really good at moving the goal posts. You should be in construction.
No biological men in women’s sports. They have an unfair advantage. Period. Double amputees aren’t allowed to run with people that have both legs because they’ve figured out how to make prosthetics better than human legs. It’s an unfair advantage. It’s got nothing to do with being trans. It’s got everything to do with keeping the playing field equal. I’m not worried about my son being beat in Highschool sports and losing a scholarship to a biological girl. I am worried about my daughter losing a scholarship to a biological boy.
I also find it rather off putting that on this issue, we have to wait until you get home to post a source. You post at work. You post other sources at work. What makes this topic so different?
There is also this, from Harper.
“There's absolutely no question in my mind that trans women will maintain strength advantages over cis women, even after hormone therapy. That's based on my clinical experience, rather than published data, but I would say there's zero doubt in my mind.”
I post links at work, I usually don't post scientific studies, which I want to read first. For this topic, I've talked about it before, I have notes.
https://onlinelibrary.wiley.com/doi/epdf/10.1002/pits.22500
a study looking at LGBTQ youths taking part in sports in general. The finding is that trans teens are less likely than cis teens to take part in sports at all, something the article believes we should make efforts to change due because school sports improve self esteem/less likelihood for depression and suicide.

An article, some data, and a study, all looking at differing performance between men and women in sports, the findings are that it's more complicated than 'men are better than women', the reality is that there are some sports where women have definite advantages over men, others where men have a big advantage. Women tend to do better in high endurance sports.

Harper on physiological changes trans people undergo during transition. Her findings are in major areas like hemoglobin and testosterone levels, trans women end up basically at the same level as cis women, their muscle mass decreases as well. A note on this is that Harper has admitted that in the studies looking at muscle mass there is a weakness in that the studies look at non athletic trans women, according to her the trans women started out with a lot less muscle mass than cis men, so they had less to lose, and which might effect the slower rate of muscle mass loss. Also, muscle mass does not necessarily equal muscle strength.
Which brings us to:
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8090355/
Which looks at muscle strength, Harper does not like this study because it's scope was limited to 8 people, but it's one of the only studies looking directly at muscle strength available. The data shows that trans women's muscle strength is in line with cis women's muscle strength.
This is also partially backed up by
https://bjsm.bmj.com/content/55/11/577
which shows that trans women's ability to perform push ups and sit ups are equivalent to cis women after 2 years of hormone therapy. It does show that running speed is about 12% better than an average cis woman, however, separately the author of this study does note that high level and elite athletes are substantially higher still, so the performance advantage is completely within the performance advantage that one cis woman could have over another cis woman.
Also, the findings on running isn't consistent, Harper looked at running as well
https://www.researchgate.net/publication/307766116_Race_Times_for_Transgender_Athletes
Her conclusion was that trans women in running do not have an advantage.
Which comes to what still is essentially the overall state of the science on trans women in sports:
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5357259/
Which basically concludes that the data available does not show a consistent, unfair advantage for trans women, and policies that sports organizations have implemented are not justified by the science.
Anyway, since it was brought up, I searched for opinions of people who actually compete with trans women, and found this:
https://bridges.monash.edu/articles...n_Sport_and_the_Pride_Cup_Initiative/12731810
Only 24% of women who actively compete against trans women believe that the trans women have an unfair advantage. For some reason, 46% of men, who don't compete against trans women, feel the same. Odd how the people who aren't competing against trans women are the ones that think it's unfair, but the ones actually competing think it's fine.
Going into policies being passed in the US and around the world would probably get very political, but suffice to say, a lot of states in the US are banning trans children from getting gender affirming care, and internationally the US is still one of the more progressive states, so, a lot of trans women will be excluded by a rule that prohibits those who go through a male puberty.
