Eric Vilain is a believer in 'gender identity'.
He's a bit inconsistent though, isn't he?
I get the impression that, in the context of sports, he is an intersex advocate who conflates and separates transgender and intersex as it suits him. He said this in 2016:
Vilain, the UCLA geneticist, sees what he calls a "schizophrenic" conflict between the Chand ruling and the IOC guidelines on transgender female—not intersex—athletes, which was rewritten in November to allow an athlete to participate in competition as a female if her testosterone is below 10 nanomoles per liter, same as the old IAAF standard. "The guidelines are very favorable for transgender athletes, and a great advancement," says Vilain. "But the same rule was struck down for intersex athletes. It's illogical."
Where, then, does this lead? Perhaps Olympic sports should establish a third gender category: intersex. A more likely possibility, given societal trends: "You put everybody in the same bag, just compete by gender identity," says Vilain. "Right now the social activists are winning. So you can have Bruce Jenner saying, 'I'm Caitlyn, and I'm competing as a woman.' Nations have a huge investment in sports, and they would do this. And that would be a disaster for women's sports. It would be a sad end to what feminists have wanted for so long."
