Again, this is a garbage transphobic argument. It leads to people questioning the woman-ness of even cis women who are good at sport. We already have problems where women with naturally higher testosterone than usual are banned from competing[1] or salty parents calling for an investigation into a child's gender because their kids got beaten in sports[2]. TERF shit like this hurts all women.
