The ones screaming transphobia are the ones not understanding biology and sports, not the ones going against the Olympic committee because a cis man played tennis against a woman once.
Repeat with me : CIS MEN AND TRANS WOMEN ARE DIFFERENT.
There is a thing called hormone therapy. It is like opposite dopping. Trans women usually have LOWER than average testosterone levels. Also sports players are the ones at the top of what average is.
If you people think because she had a male puberty she still has advantages than I guess cis women should start taking dopping at that age because every single dopping test is only for a few months
This isn't just about test levels. Bone density, power output, muscle fiber activation/recruitment, etc. Men have biological/genetic advantages in strength and power output. Point. Blank. A woman will not be able to match a man when it comes to these things. Especially if they don't start hormone therapy before puberty hits (Male or Female).
Of course, there will always be outliers in populations, but the fact still remains.
It. Is. Not. Just. About. Testosterone.
