I remember some kind of testing on certain athletes in the 70’s and 80’s.
They have always had to deal with folks who have this disorder in women’s sports.
However women have been competing in the Olympics since 1900. They have not always done genetic testing.
The modern way this has generally been delt with before all the trans insanity was simply by testing testosterone levels of all women, as long as it was below a certain threshold they could compete.
Folks who have this disorder are not remotely pushing or part of this trans insanity, that’s wholey a byproduct of the homosexual activist groups
