I'm not talking about the "some experts", "some scientists", etc. etc. I'm talking about real science without the human bias...
Transgender male swimmer, Iszac Henig, struggles to compete with male swimmers in the 50M freestyle. Henig was an All American when She/He was competing as her biological gender. Now, swimming for on the male team, she managed to not finished in 79th place out of 83. The 4 males she beat include one without a forearm (who had competed in the Paralympic Games) and the other three specialized in breast-stroke (one of the slowest swim style)
While her counter-part transgender female, Lia Thompson, swimming in the women league is dominating and breaking all collegiate records.
I'm not against anyone becoming whatever they wish, even being an animal (furries)... However, no biological male should compete in biological female sports and vice versa. Why even have male/female sports then if you allow it? Why not just let women and men compete together.
