1. The transgender athlete won't seem to die. This is so frustrating, because from a logical standpoint, the answer is so freaking obvious: the current system is not broken. It does not need fixing.

2. Quick test: name a transgender Olympian off the top of your head. You can't, because since the IOC started allowing transgender people to compete in 2004 there hasn't been one.

3. The NCAA has allowed transgender people to compete without surgery since 2011, and there has not been a single dominant transgender athlete anywhere in college sports.

4. These constitute large scale, longitudinal tests of the system with millions of athletes as a sample, and the IOC and NCAA rules for transgender athletes are clearly sufficient to preserve the integrity of sports at this time.

5. 15+ years and millions of test subjects is bigger, and longer, than any clinical trial of a drug that I can think of. The development and deployment of the F-22A, the world's most advanced stealth fighter, lasted roughly as long.

6. The clinical evidence and subject matter opinion aligns with the observed results: removal of testosterone for a year is sufficient to remove competitive advantage. In terms of testing this hypothesis, there is literally no disagreement between various results.

7. The arguments from the other side are either anecdotes (What about so-and-so who won some mid-level event?), or are a form of fearmongering (Transgender women will start dominating women's sports in the future!) that ignores the large scale, real world testing of the policies

8. The implied "solutions" of "Well, they can compete against men or get their own league" replaces a speculative harm with an actual one, because no harm to sport is happening now, but either of the proposed "solutions" represents a de facto ban on transgender athletes.

9. Testosterone, which the NCAA and IOC regulate, is a key factor in performance. Because trans women lack it, they cannot hope to compete against men.

10. And there simply aren't enough transgender people for them to "get their own league", nor would there be enough public interest to fund such events even if you could find 32 world class transgender fencers. Or 16 crew teams, etc...

11. On top of that, segregating transgender people from society, and driving them from public life, is what the right wing wants. When asked about transgender people in 2016, Ted Cruz replied "Can't they just do that in their homes?" Separate but equal never works out that way.

12. If, at some point we start to see a disproportionate number of transgender women winning high level athletic events, then it would be appropriate to reevaluate the rules for participation. But for now, there is no data-based evidence that the system is broken.

13. Athletic leagues do this all the time: if something is giving people a competitive advantage, they ban it (but not the players, unless they cheat on the new rules). Steroids, weird golf clubs, aluminum bats, corked bats, intake manifolds with laser holes in them....

14. I'm frustrated as hell that we're still fighting this battle. The empirical evidence all points one way. We have years of data and huge sample set. The alternative is hurting a minority group for no measurable gain (you can't have less than 0 trans Olympic athletes)

15. So, when I point these things undeniable facts out, and people still want to argue, I have no issue with calling them bigots and transphobes. They are immune to facts, logic, data, and expertise. But they are willing to hurt trans people based on their own "gut" feelings.

16. Oh, and Renee Richards was 40+ years ago, never ranked higher than 20th, never won a major event, and Martina Navritilova beat her all three times they met. Fallon Fox never made it to the big leagues, lost once, and is retired.

17. The woman who complained about Rachel Evans winning, had beat Evans in 8 of the 11 events they had met in previously. And with that, I just summed up every major female trans athlete in the past 40 years. This isn't a big enough sample to decide ANYTHING.

18. We have thoroughly field tested the hypothesis that transgender athletes will dominate if they are allowed to compete, and statistically we can reject this hypothesis with high degree of certainty. (I'll do the math and display it for you if you really want).
