No, we absolutely should not mark the records of known transgender athletes in any way. Because once you start down that road you wind up asterisking cisgender athletes whose development is outside the norm.

We could get into a long discussion of transgender persons who do or do not undergo HRT, or how there are already rules against transgender women competing professionally if they aren’t on HRT, or whether or not such rules or gendered sports at all are justifiable.

But all of that is just a distraction. The elite in any competitive sport are ALREADY several orders of magnitude beyond the norm, to the point where any advantage a trans woman might have for going through male puberty is essentially a wash with “are you just naturally well-formed for this sport”.

It’s worth noting, by the way, that there ISNT broadly an athletic benefit to having gone through wrong-gender puberty before medically transitioning. Plenty of athletes have done exactly that, and as far as I know exactly none of them wound up being relatively better among their true gender peers post-HRT than their standing among birth-gendeR peers pre-HRT.

And there have been more instances of cisgender women being wrongly accused of being trans than there are transgender women athletes at all.
