Even in sports where women are successful, elite sports women repeatedly report kit that isn’t adapted for women, lack of training facilities, lack of coaching, poor or no pay, etc etc
This reminded me of the excellent speed by Victoria Hood at the A Woman's Place is on the Podium event last year.
There she describes the massive difference between the cycling world opportunities between men and women.
As a female you're lumped with one of two bad choices, both of which are covered in that speech - try to join in with the males - but you're physically out of your depth and just can't compete, or try to set up your own female events and training programs, but be unable to get the same level of support.
People like SodaPerson probably see the second bad option and in some utopian fashion think that just removing the female separation will help because women will now benefit from all the male competition and male facilities. Utterly deluded. Sure, they'll have the theoretical possibility to be there alongside the men, but in practice no woman would ever reach international level in any physical sport.
And knowing that would stop many women from even attempting to start the sport in the first place. No Olympic fantasies for girls permitted.
