What about your completely androgen insensitive XYs? Phenotypical females but XY.
Just being nitpick to underscore how difficult it can be to appreciate all cases when making rules. I agree with others that we should probably just leave it up to the individual associations.
I appreciate the nitpick as I can clarify my "simple fix".
That's the simple thing about my measurable "system", that person still has 2 options where their sports eligibility is funded through taxes (the crux of the issue and why it's even "political" at all).
Try out for XY Division. Can't make it?
Try out for Co-Ed Division. Can't make it?
Find another non-taxpayer funded sports association, hence open to anyone and everyone,
and not at all eligible for political legislation/debate. Done and done.
(Let's be clear here, if you can't make the XY Division or Co-Ed Division as an XY, you're probably not "good enough" to make the XX Division either, as the XX Division isn't "inferior" to the XY or Co-Ed Divisions. XX athletes who "make the cut" are at the top of their Divisions and saying that a "weak" XY is comparable to a XX "athlete" is arguably sexist on its face, not that I'm saying you are anyone else is making that argument).
The "problem" continues being solved without tossing another red meat issue to the deplorables who are only using the issue to recruit people to murder liberals in their sleep (that's the real endgame with all of this, don't miss the forest for the trees, etc.).
This "issue" is about as important as my favorite brand of deodorant or some random person's favorite color. Making it a whole "thing" is exactly what the right-wing authoritarians want, and we can have a simple "workaround" that can avoid it being another division that peels away "sane" people to the side of fascists.
I understand that there can be "sides" and discussions and reasoning for 200 ways to split up athletes into various divisions, but as catastrophic collapse continues snowballing, I'm more interested in putting out some inconsequential ember so we can focus on the planet-encompassing fire.
