Right, and I mean even cis women are not all the same. For example you say you want to have a small frailer body. But I'm a cis woman and I'm the height of the average man (5' 10") and while I have a very "feminine" body shape, I'm not small or frail by any means.

There are cis women who are as the Aussies say "built like a brick shithouse" (ie very stocky and strong). There are cis women who are incredibly tall. The average Jamaican woman is taller and stronger than the average Filipina woman. Is it unfair to Asian women that African women are allowed to compete against them? No one would argue this. Sure some people are born with athletic advantage. But that's true for literally everything. Testosterone is only one factor. But it's seemingly the only one people have an issue with. Why? Because of transphobia I guess.

I also think separating competitive sports by gender is a stupid idea but that's another argument for another time.
