How best to stop excluding trans kids from sports?
Good question! Nothing should stop anyone, including transgenders from playing the sport that they wish. As long as of course they do not physically or biologically create an advantage for themselves, and disadvantage anyone else and follow the guide lines of the sporting administrators and scientific and medical advice to that end.
The problem exists though, that scientific and medical knowledge is far from certain in this subject. Perhaps do get a clearer picture, we may need to wait a decade or two. Thankfully, though, the aspect of transgenders is relatively rare, and the percentage of those that want to take part in a sport, obviously even rarer.
In summing, striking the balance of fairness and not having an advantage in sport, and the rights of the transgender athletes, will not be easy, and pleasing every one, particularly male and female competitors, will be even harder.
My thoughts actually go back to the covid 19 hey days, and the screams and whinging from anti vaxxers losing their rights with mandatory vaccinations, against the rights of all other citizens to remain healthy and safe by the best means possible. I see a somewhat parallel there.
As was linked to and showed as fact in the other similar thread, boys and girls play both rugby codes together up until the age of 10, where under the existing rules, following medical and scientific advice, they then separate and segregate according to sex under scientific medical advice, particularly in body contact sports.
The gender neutral and selection by size and ability claim is a furphy, particularly when obtaining late teens and adulthood, and as explained and reasoned in the other similar thread.
Probably the best outcome as far as I can see.
Under scientific and medical advice of course, although this as yet has not not fully decided and is somewhat limited.
