Ah, well, posted on the poll thread, thought I'd follow the 'discuss elsewhere' direction. Did read half this thread the other day, hence knowing what the issue is.
It's clearly madness because gender is not sex and sport is segregated by sex. The end.
By all means have, display, live according to whatever gender identity you like. Be a person, in whatever way you wish, so long as in doing so you do not harm other people. Generally, let's be excellent to each other. (This does involve considering the basis and consequences of our wishes and actions, sometimes consulting the people affected, who may have needs, rights or a perspectives we hadn't thought about, obviously). Lovely.
My mind jumped straight back to reading my mother's old copy of The Female Eunuch 25 years ago - the underlying issues are not new - wherein men are men and women are anything other, lacking full agency, done to. It seemed very old fashioned then. Germaine argues that women are actually, postively, definitively, actively women. (Well duh, I thought). She has of course lived that belief in arenas more nuanced than sport.
Also, the Handmaid's Tale. What really lives with me from that story, is the ease with which men; normal, nice men, allowed women to be oppressed. Gradually colluding with their oppression, initially just by turning a blind eye, or noticing and saying things were indeed a bit off but not making it their priority to do anything to address that.
'First they came for the athletes but I was not an athlete, so I did nothing...' It's easy not to when you think your rights are unassailable, that you live at the centre of a strong and generally fair democracy, that you are the very subject, your well-being the purpose of that democracy. It's easy to think things will get sorted out, because if there is an injustice, the people affected will fight it and justice and common sense will prevail.
Something quite long could follow that, so I won't.
Then, there was Pistorious. Paving the way for athletes with a difference to challenge official boundaries. Really interesting how in his case, everything was about proving equivalent physical ability. Having to prove that his difference did not confer any advantage, at all.
Let's start from the same premise. Fair, surely? You want to compete in a certain class. You prove, exhaustively, against all reasonable challenge and scepticism, that your difference confers no advantage upon you, over the other competitors in that class.
There was no doubt that Pistorious wanted to compete as if he was able bodied. Did he miss a trick? Should he simply have said 'I believe that I am able bodied (contrary to appearances, I know), I feel able bodied, I identify as able bodied, I wish to live as an able bodied person'?
Well that wouldn't have been on at all, without proving equivalence first, because he could have been the very best at his sport; won records, prizes, pushed out people who were actually (without his possibly unfair advantage) the best. No.
But pushing out the best women is just displacing mediocrity, isn't it. Who cares if one lot of second class competitors are better than another? They're still second class, other, never going to be the best .
