i think science has come a long way since the 1950s.
Sports should get away from gender definitions and go with genetic and hormonal standards.
If someone is producing "Male level" testosterone, has "Male-specific" chromosomes, etc., it shouldn't matter if the individual also has female body parts.
Label them male and female if necessary, but use science to determine when someone has the chemistry and DNA to develop the bone and muscle density, lung capacity and body size of an adult Male.
We as humans have the intellectual capacity to treat this issue logically, yet there are people who only see it as an identity issue requiring gender affirming care and acceptance.
Please, send me to planet Vulcan where logic and reason are still practiced!
Why is there a weight class for physical contact sports, but we've turned a blind eye to gender-related advantages?
