I quite literally have no idea what you're talking about.
I know. It's hard. Ever heard of the gender pay gap? It's quite a thing in corporate life. Women are paid less than men, apparently. But they also produce less than men. They work fewer years during their lifetimes (maternity leave), fewer days per year, on average (sickness absence), and fewer hours per day (higher ratio of part time work). They also tend to work in indirect labour roles such as HR or admin. Direct labour (hod-carrying, ditch digging, climbing telegraph poles, felling trees) tends to be done by men. And this is where the value is actually created - certainly in manufacturing, energy, mining, agriculture. [Side note - I accept that there are many roles where women outperform men and many industries where women outnumber men too - I'm not arguing that this is absolute and universal]. But we have laws, and customs, that tell girls they can grow up to do anything just as well as men. We have laws, and customs, that require employers to ignore the differences in performance that can be attributed to sex, and to pretend this distinction doesn't exist. We do that because it makes society a fairer and better place. Men benefit from this too.
So when it's access to employment, why is it that we agree that the obvious sex differences can simply be overlooked, but when it's sports, sex differences are the most important thing to focus on? We already know that in many sports factors such as age, height and weight matter, and actually matter far more than sex - and these are already split into divisions and classes that reflect this. So why the obsession with making sex differences the primary discriminator under all circumstances at all times?
