I never said there aren't advantages there, just that they don't mean that much in the grand scheme of things. There are plenty of other factors that go into success with any sport, for example this quote from the article from The Nation that I linked to earlier:
I contacted Dr. Nicole LaVoi, director of the Tucker Center for Research on Girls & Women in Sport about the way ignorance fuels the fires against these athletes, who told me: “Unfortunately, the backlash surrounding both athletes is in part due to lack of education and factual knowledge about transgender individuals. Both girls are on hormone suppression, which negates any competitive advantage due to testosterone, but most people are unaware of this fact. There are many factors that go into athletic performance—for example, to name a few, physical training, conditioning, dedication, motivation, quality of coaching, nutrition, and psychological skills that get erased when the sole focus is on gender identity and hormones.”
Hormones are a factor, but they aren't the only ones.
