I don't see that. Are they even trying? Is the question to ask. You've got levels and levels of participation in every sport, after all.
So if there's a transman with a liking for sports, a talent, a skill, then where are they seeking to compete? Are they almost always going back to the women's category as they might have in their pre-transition days; or are they now, post their transition, competing against cismen? If the latter, then the inclusion argument is at least honest.
Perhaps I didn't make my point well. So I'll be more clear:
We will never be able to tell if transmen with a liking for sport are seeking to compete.
We won't be able to tell, because even if they are seeking to compete, they won't be competitive - they won't make the cut. Because they are female. They can seek to compete and try out as much as they want to... but they won't be successful.
Time for another attempt at a bad analogy, to try to demonstrate the dynamic I'm trying to highlight.
Let's talk about competitive can stacking! Let's say there are two leagues - one for people under 5'5", and the other for people over 5'5". The Under 5.5 league stacks on the second shelf of the grocery store. The Over 5.5 League stacks on the third shelf of the grocery store, which is a foot and a half higher than the second shelf.
Now, both of those categories contain people who are very competitive against each other, as well as people who are not competitive. The non-competitive people don't make it past try-outs, and we never see them again. But both groups also contain a handful of people who identify as a member of the other category. In colorful language, there are some transshort people and some transtall people.
Now, let's assume that the transheight people argue that the leagues should be inclusive of everyone's height identities, and should allow transheight people to compete on the team that aligns with their height identity. So the governing body for competitive can stacking thinks about it and says "Yeah, okay, we think inclusivity is a good idea, let's give this a shot, what could go wrong?"
Now let's put it into play. We've got trials coming up for each team, and each team can have 10 stackers. There are 25 cisheight people and 5 transheight people trying out for each of the two leagues.
Let's first look at the Under 5.5 tryouts. For that, there are 25 cisshort people and 5 transshort people. All of them, can reach the second shelf, where the stacking takes place. So for the Under 5.5 league, there are essentially 30 people trying out for 10 spots. Each of the transshort people has a 1 in 6 chance of making the team.
Now let's look at the Over 5.5 tryouts. There are 25 cistall people and 5 transtall people trying out. But here's where reality interferes with the noble ideal of inclusivity:
The 5 transtall people cannot reach the third shelf. That means that none of the transtall people will make the team, even though they tried out in numbers equal to the transshort people.
At the end of the day, we're going to see an Over 5.5 League that is comprised only of people whose objective measurements are over 5'5" tall. But for the Under 5.5 League, we could end up seeing two people on the team whose objective measurement is 5'10 and 6'2.
Do you get where I'm coming from? Even if the impetus is for inclusivity, we will never be able to tell from the outcome. Because no matter how they identify, no matter how tall they envision themselves to be, the 5'2" tall people
cannot reach the third shelf.
No matter how strongly a female might identify as a "man", they are still fundamentally female. They aren't going to make the cut to join a male team.
We will never be able to tell whether argument from inclusivity is genuine or not.
As I see it, there have been three arguments put forward for/against this thing, the sports thing. One, inclusion. Two, fairness. Three, what sells, what people will pay to watch. This addresses only the inclusion argument, not the other two. And even then, this does not necessarily address the merit of the argument --- that is a separate matter, a more multi-dimensional matter, when you think about it --- but this does make for an easy way to determine if the inclusion argument is being put forward sincerely and honestly or not, or if it was never meant as anything other than a smokescreen for basically grabbing prize money by playing on easy mode.
It doesn't though - we cannot tell whether the inclusion argument was initially meant sincerely or not. It very well may have been intended with completely honesty and sincerity... but the outcome makes it impossible to determine.
And when it comes to athletics, males and females are NOT athletically equivalent. It's not a complete parallel to the transshort people who can reach the second shelf easily, but have no inherent stacking advantage. When it comes to sex, males DO have a material physicals advantage over females.
And we've seen the result of this disparity multiple times. We've repeatedly seen middle-aged males who are not in top shape, and who were mediocre or non-competitive against other males... come in as top-placing winners when they compete against females. We've seen it in weightlifting. We've seen it in swimming. We've seen it several times in cycling. Laurel Hubbard, Lia Thomas, Rachel McKinnon, Austin Killips, Emily Bridges, nd several others I can't remember right now. All of them were mediocre or completely uncompetitive against males. And all of them took winning spots from females who were at their physical peak.
