Research has shown that trans women are on par with cis women within a few years of HRT. The idea that we possess some male advantage is a transphobic talking point designed to make people not see us as women. And “biological male” is a dogmegaphone, implying we are never really women.

And from what we see of most trans athletes who do get to compete, they’re not the top in their field. So that puts another nail in the coffin of the idea that trans women have an advantage.
