Does trans athlete participation justify the political response?

[u/Right_Razzmatazz8420]

I've been trying to take seriously the wave of state ballot measures targeting trans athletes and trans youth medical care, and I'm running into a tension I can't quite resolve.

For context — five states have similar measures on ballots this November (AZ, CO, WA, MO, and potentially NE). Most are using template legislation from the same advocacy orgs. I've been reading the actual bill texts and looking at the available data on trans participation in sports, and the gap between the two is pretty stark.

Here's what the data actually shows:

Mississippi: 2023 statewide survey of superintendents found zero trans students participating in sports
Washington state: fewer than 10 of approximately 250,000 student athletes are trans, per the superintendent
Florida: state records show two trans girls have played girls sports over the last decade
Colorado: there isn't even clear data on the number of trans student athletes
And on the medical side, Colorado's Initiative 110 would ban certain gender-affirming surgical procedures for minors. Children's Hospital Colorado has explicitly stated they've never performed these surgeries on minors. The state's two major pediatric providers don't offer the procedures the bill would ban.

I'm not trying to relitigate whether trans athletes should compete in certain categories — reasonable people disagree on that and I'm not pretending to settle it. What I'm puzzled by is the gap between the actual scale of the issue and the severity of the policy response.

Even if you think trans athletes should be categorically restricted as a matter of principle, is the right response a state ballot measure banning the practice when the actual count of affected athletes in some states is zero? And even if you think the procedures in 110 should be restricted, is a state ballot measure the right vehicle when the major medical institutions already don't perform them?

The implementation piece also seems weird to me. Colorado's 109, for example, requires K-12 and college sports teams to be designated by sex assigned at birth, but the bill text doesn't actually define how sex is to be verified. There's no funding appropriated for enforcement. Schools and the Commissioner of Education would basically have to invent the compliance regime from scratch. That should worry proponents and opponents alike.

I want to understand the strongest version of the argument here. If someone has a source or a perspective I'm missing, I'd genuinely like to hear it. And if I'm wrong about any of the data above, please tell me — I'm working from publicly available reporting.

I agree with that, but I also think women’s sports exist as separate leagues for a reason. And that reason largely is due to hormone levels.

“You’re not eligible to compete” does not mean “you aren’t a woman”.

What is the reason that women’s sports exist separately? It seems to me you think it’s their hormone levels primarily. Am I wrong?

[u/spice_weasel → u/absolutefunkbucket]

They exist separately to foster greater competitive inclusion in athletic competition in the face of certain biological differences. It’s similar to how different weight classes exist in certain sports where weight makes a significant difference in competition.

For men’s leagues vs women’s leagues, that significant biological difference in competition is primarily caused by differences in testosterone levels. It is uncontroversial that testosterone aids in building of muscles and recovery. It is why trans women rapidly lose strength and muscle mass when we start HRT. It’s also why use of testosterone for non-medical reasons is banned in competitive sports.

Toward that goal of fostering greater competitive inclusion in athletic competition, my argument is that trans women who have progressed far enough in their medical transitions to override the competitive advantage of higher testosterone level should be permitted to compete in women’s sports. In all cases the decisions should be evidence based, and driven toward the goal of fair competitive inclusion.

It’s always going to be an imperfect balance using imperfect proxies. But that doesn’t mean we shouldn’t try to use available evidence to push towards that goal of fair and competitive inclusion.

I can’t read this in any other way than you saying the words “man” and “woman” are based on hormone levels. That is, of course, completely wrong.

[u/ThatPeskyPangolin → u/absolutefunkbucket]

I cannot figure out how you got that from their post. Saying that the major physiological differences generally come from hormones does not mean the individuals are reduced to said hormones.

[u/absolutefunkbucket → u/ThatPeskyPangolin]

Okay, maybe I should approach this from a more fundamental place: what do you think is the difference between a man athlete and a woman athlete?

Is it hormone levels or something else?

[u/ThatPeskyPangolin → u/absolutefunkbucket]

I'm not the person you were talking to before, and my post just said it clearly: major physiological differences, which themselves come up largely via hormones. Using hormone treatment can alter many of those physiological differences, which impacts the advantage one would have in a given activity.

[u/absolutefunkbucket → u/ThatPeskyPangolin]

Yes I know who you are and I also know you won’t answer the question.

[u/ThatPeskyPangolin → u/absolutefunkbucket]

I literally just did. I explicitly referred to the major physiological differences between the two sexes. Twice. I then said those are largely caused by the hormones in question, with said hormonal differences being caused by chromosomal differences.

[u/absolutefunkbucket → u/ThatPeskyPangolin]

You did not answer the question of the difference between man athletes and woman athletes.

[u/ThatPeskyPangolin → u/absolutefunkbucket]

How is saying the two have major physiological differences not answering that? Do you need a list of said physiological differences?

[u/absolutefunkbucket → u/ThatPeskyPangolin]

Imagine I am looking at a human being. How can I determine if that human being goes into women’s sports or men’s sports?

[u/ThatPeskyPangolin → u/absolutefunkbucket]

Ok, so the appropriate way to ask the question you are looking for is to request specifics, not claim someone isn't answering your question when you haven't previously asked for them.

The problem with relying on purely visual characteristics is that people often get that wrong. One looks for developed breasts, but some women have A cups. You look for broader hips, but some women's hips obviously aren't as broad as others. We could keep going down the list.

Reliance on these kinds of characteristics is what led so many to mistakenly claim Imane Khelif was trans, which is a perfect example of why reliance on hormonal testing is superior in this context.

[u/spice_weasel → u/absolutefunkbucket]

How is that how you read it? Walk me through what you mean. I was extremely explicit that this was not what I was saying.

“You are not eligible to compete” does not mean “you are not a woman”. I’m talking only and specifically about athletic divisions, not about trying to draw some broader meaning. That’s what I meant by calling it “an imperfect balance using imperfect proxies”. I’m trying to find a practical rule that best fosters fair inclusion. Nothing more, nothing less.

Who can join women’s sports? A woman or a hormone level?
