Sacred Haven of Debauchery

I will answer only once, Nebok, to clarify my position. There is no need to respond further, as I don't particularly want to engage in a lengthy discussion.

Why remove it?

Because it will increase competition in sports. Contrary to stereotypes, the difference in physical strength between men and women is not that great (not to mention that women are more resilient than men). At one time, studies were even conducted comparing the abilities of men and women with equal physical fitness. And the results showed that the main influence on physical strength is not gender, but height.
Some people, with a very rich imagination, like to imagine an absurd scenario as a counter-argument, such as a girl weighing 60~ kg boxing against a giant weighing 120~ kg. It goes without saying that anyone who has even a superficial understanding of boxing knows that athletes compete against people of similar weight categories?

And who will be happy?

People who advocate for gender equality, especially sports enthusiasts.
