I see what you are saying, but I would rather believe what Nigel Short is saying about women chess players and the international chess ranking, which is shocking for the equality supporters. Also, your statistics are all wrong, the same amount of men and women try to participate in chess, with the same equal opportunities of training, but practically no women make it to grand masters. Interestingly, Nigel Short has a theory of women being risk averse, having lower testosterone levels, which is exactly what makes them far superior and cautious surgeons (apart from ortho) than men.
Equally, no male nurse or nursery nurse has ever been allowed to come anywhere near my dc. My dc, my choice. (Did we have some shit female nursery nurses and female medical nurses - yes, of course).Those males in caring professions have the right to do whatever they want, and equally we have the right not to use their services.
"any woman who has the physical ability to match the minimum required for the job and wants to do it should not be rejected because of the prejudicial belief" - I am sorry, bugger that for a game of soldiers, they can indulge in their physical strength equality fantasies, but not at my expense - a female plumber came out to my aunt to fix things - not only was she clueless and useless, but my aunt had to help her take the boiler down because the lady was not strong enough - and my aunt has a hernia and is not allowed to lift anything heavy. Unfortunately, my aunt was to polite to ask for a man and she was hospitalised, what a sacrifice on the alter of equality, damn it. (Same nonsense with female hand-to-hand combat soldiers - good luck to them if men in nighties and flip-flops saw off the UK and US male soldiers in Afghanistan).
