I hate talking about these issues but they are important and need to be addressed.
I hate talking about them because I do believe that trans and intersex women ARE women. But they are women with an advantage in sports that is (in my opinion) unfair. Now I want to be clear. I hate that I think this. I have tried very hard to unthink this. I have read arguments from trans activists and athletes. But I've never been truly convinced.
Gender is a social construct. But so are sports. Women, or Cis Women at least, when they fought for the right to play, they didn't fight for the right to play WITH men, and that was for a reason. It's one of the only 'separate but equal' civil rights movements I can think of.
Now taking trans and intersex athletes out of the equation for a second, I don't know what makes cis men better athletes than cis women. Testosterone? Bone density? Lung capacity? All of the above and more? It's clear that there's not an answer for that right now. But pull up any XC or track meet. Any one you want. middle school. high school. college, professional--you'll see the same thing. Males far exceed the females in performance every single time.
As a cis woman, I was a decent competitive runner. There is an argument that because I was faster than some males than there's no true competitive edge. But I had accomplishments. All State and whatnot. Line me up against an All State boy, well....the race is won probably in the first 200 meters.
The thing that this ultimately comes down to for me is that while I do believe that trans and intersex women have an unfair advantage over their counterparts, there is no solution that I think is humane, just or fair. Caster taking drugs she does not need or want to take? Like...seriously who would do that??? And I don't think it's fair to say 'wellll she can compete with the men' or 'wellll she can run the 200'. She ran the 800 already, she's competed in it for years. She's not going to change her whole life around without a dang fight.
I also despise the idea of excluding trans and intersex women from sports. Sports is a social construct that is supposed to celebrate hunanity, not exclude or dehumanize people.
Ultimately, I hope I am one day convinced that trans and intersex women do not have an unfair advantage. That would be mighty convenient for me.
