I am sure that the author of this article absolutely believes the bollocks they wrote, but they keep using false arguments as some kind of wisdom. It is like they refuse to believe that these repeated solutions are not solutions at all.
Not only that, but we already have 'mixed sex' categories in many sports. This author is suggesting this as some kind of great idea.... when it is already being done. And is fine for those who wish to compete in that way. It defies logic though that this writer understands that including a person who is male into a competitive team event as a female athlete is still unfair to the other teams following the rules with the regulated number for each sex. That solution doesn't work because the male athletes still want to be treated as it they were female athletes and therefore the teams are unbalanced.
The weight divisions argument has been modelled and found to not produce results that equate to female people having fair competition. Yet, people who are unable to see past this supposedly clever suggestion keep doubling down on it being a solution.
All based on the false premise that sport can be fairly divided by 'gender'.
