I just don't think I agree with this though, and maybe we'll just stop at a fundamental disagreement.

Again...

• pairing different general body types in weight classes where applicable

• as well as the potential for that general physicality test to set a minimum for a league.

• plus time to normalize true co-ed competition where folks grow up knowing nothing else but normal and aren't stigmatized for developing their body to fit a given sport's ideal need.

The third one probably asks the most of current society (though that's a sad comment on society) in having to accept the appearance of someone actively acting against currently socialized standards of attractiveness associated with assigned sex. But if we could trying embrace those three, my personal hypothesis is that things would level much more than most expect.

The true and only reason that we don't do this, is that it would label those bottom third or so of males that fear they would be labeled as "less capable than a girl!". Whereas now, even the worst players on the high school football team can usually get on the team and wear a jersey around campus, regardless of if they ever actually get into games. That kid's bigoted parent will fight to be sure "their son's spot" is not earned by a more capable birth assigned female.
