On the one hand that’s supposedly to do with competitive advantage. It makes sense to try to even the playing field, which should have nothing to do with objection on ‘moral’grounds. I’d argue this is mostly a good thing given the iffiness of many groups’ morals.
Case in point, your exact examples, which brings me to the other hand. Banning trans athletes on ‘fairness’ grounds is bullshit. In most sports there’s no known competitive advantage. Where there’s an imbalance they tend to show disadvantage. The rare cases with an advantage for trans athletes tend to disappear the moment you correct for size/weight, which is not something we’d exclude cis athletes for. None of your examples should have happened. They do not hold water on fairness grounds, and any moralistic reasons behind it are reprehensible.
Hah, reading this not too long after watching Freya Holmer’s latest video/talk is fun. “Everybody is disagreeing, except everyone is agreeing that unreal is wrong”. The image is by her (it’s also used in the presentation). And she mentioned wanting to make it easier/possible to change handedness. She’d already had an ‘apology’ from Sweeny for the Unreal configuration. Interesting to see they’re taking it further than that.
