"Supporters of these measures say they protect sports for cisgender girls and women."
No, they clearly state they are protecting sport for female athletes. I've never seen supports of women's sport use the "c!sgender" pejorative. Most female athletes are not "c!s" as that requires them to have an imaginary "gender identity" that most believe to be ridiculous.
"They say transgender female athletes have a biological advantage. (The science on this is unsettled, and the studies have only examined adults, not children or teens.) Mills said Thomas won because “her reach was several inches longer” than other swimmers’."
They say male athletes have an advantage, which has been proven through over 150 years of athletic records.
