The thing is, we shouldn't have to speculate, because the IOC and other sporting bodies should not permit any loophole that allows males, including those with DSDs, into female competitions. Not only because of male pubertal advantage, but also because of taking away women's rightful places.
However as we know, the IOC does't care about protecting women's sports. We know that they have allowed two males to compete in the women's competition.
I don't want to speculate; I want to be able to trust that the competition is fair, because it is regulated, and because there is consensus on what is fair. However, when I can't trust the authority responsible for ensuring this, I will lean towards trusting my instincts. This doesn't mean that I trust I am able to accurately sex 100% of people. I don't think that. More that I trust that where I sense a disconnect between what I read and what I see, in some cases, I will be right. After all, there is precedent for it.
I think the media should be exposing this scandal, rather than cloaking it in obscurity and scientifically unsound misinformation. Journalists are not doing their jobs; but also, they are restricted in some ways. Realistically they can't speculate about athletes' sex either.
If speculating on here exposes the likelihood of this unfairness being far more widespread than just two athletes, then I am okay with a little speculation. Doing a bit of research this afternoon has really opened my eyes.
