Some interesting points, not least that you "could" have been the next Billy Elliott! :)
Iwon't go into the whole qualifications issue - that's another topic that can go on!
I think it's over-analysed whether women are CEOs of FTSE100 companies. There may well be a whole load of women who are capable but don't get the top jobs; there are also men who are capable that also don't get the top jobs. At present there are more men than women, but the landscape changes and evolves - the likelihood is that most CEOs will have worked their way to the top (as they should) and women now have the same opportunities as men to do so - that's enshrined in law. What should be noted is that simply being a woman doesn't make a person more or less capable of being a CEO, so the gender factor is irrelevant. Unless there is proof that a woman has been turned down for a CEO position BECAUSE she's a woman, it's just supposition and conspiracy theory at best, and a weak excuse at worst. It smacks of an Ali G type approach. Or worse, and Ali Desai approach (worth Googling).
Being on the front line clearly does appeal to some people.But again, I'm yet to see or hear of a feminist pushing for more females in coal mines, or cleaning sewers. Or scaffolding - when did you last see a female scaffolder, let alone a team of scaffolders with 50% females.
I think you make an interesting point about role models, but I think you give it too much weight. I doubt whether Asian kids turn there nose up at football because Beckham or Ronaldo or whoever is not Asian; in the same way I don't believe that many Korean kids suddenly took up football when there emerged a few well-known Korean footballers. More likely the attraction with football is the perceived fame, stardom, wealth etc.
The community influence is more of an issue. I remember some Asian friends inviting me to the local hockey club (they did a great curry) and nearly everyone there was Asian. But I think the community influence is more to push kids towards a specific sport, rather than away from a specific sport. That's my take on it.
My point remains - anyone can play rugby, they just have to want to.
Good luck with the pas de deux and the pliets :)
