Unfortunately, it’s not zero stakes with high school athletes looking to get scholarships and schools making money and funding from football. To say nothing of parental egos. If only it were as easy to sweep under the rug by claiming it isn’t worth caring about.
This is just the tip of the iceberg, too. So much of life is nearly divided up into make and female without thinking about what constitutes an advantage. Maybe basketball needs to be divided into two leagues for over and under 6’6". Perhaps hockey should be split by bone density. Or whatever, but my point is gender is a big dividing line for our society and we are attacking that line. It’s going to be messy.
I predict the eventual result is to no longer have gendered competitions at all. Which in some ways is good but would likely result in much lower participation by women in certain sports.
I support trans rights and IDGAF about sports, but I don’t see any clean way out of this mess. Something fundamental is going to have to change to answer this issue.
