I can't pretend to be a football fan but I really don't see any reason why female footballers have to be less skillful than male footballers. Yes, men are genetically more likely to be stronger and faster but women will need just as much actual skill when playing. Many girls and women do enjoy football but yes obviously more boys and men take an interest in it but this is again to do with children being brought up expected to follow traditional gender roles. Boys get encouraged to like football from a young age whereas girls get encouraged to like dolls, fashion etc. If young girls were given more opportunities to do football then more of them would grow up interested in it which would create more future female football players and female football fans. The girls were never given the opportunity to do football in sports lessons at my school although quite a few of us played it at break and liked it. The boys on the other hand did it at every week. You've picked the very specific example of football which had a very big gender imbalance due to many different factors. Is Serena Williams much worse at tennis than Andy Murray just because she's a woman? Looking at the many other careers outside sport, do you think that women are just worse than men at business, politics, law, science, banking etc.?
I'm not suggesting women should be forced to do science careers or subjects. I'm saying that women should be given equal opportunities to succeed at careers in science and industry if they do go into them. Women do go into these careers but they often don't have the same opportunities when competing to get the best jobs and also when trying to get promoted to higher level jobs once they do work for a company. It's a catch-22 situation as well because for example my mum works in a STEM field and although she's been successful she's faced loads of sexism and discrimination and has had to work much harder than the men she's worked with in order to succeed. Consequently, she said to me "By all means do Biochemistry at university but don't work in industry after you graduate. Do post graduate medicine or law or something so that you can work in an area with better gender equality". It is also true that girls are often not encouraged to take an interest in science in the same way that boys are. This works both ways for example I had a male friend who was forced by his parents to take science GCSEs and A Levels when he was much more interested in English etc.
What you've said about Cambridge admissions statistics isn't true. For 2014 entry, which is the most recent year that the statistics have been published for as far as I can see, 59.2% of the applicants for Natural Sciences were male and 40.8% were female. 60.3% of the students that were accepted were male and 39.7% were female. These percentages are very close to being equivalent and a similar pattern follows for all of the STEM courses.

Women take more sick days on average than men. Should a company be able to just hire men and discriminate against women because of that? Lets take another example, men are more likely to be peadophiles therefore were Andrea Leadsom's comments that men should not be hired to do childcare okay?
No, I haven't studied Economics but I have studied Biology, Chemistry, Physics, Maths etc. and I've read widely about this and looked up studies and research. Studying AS Level Economics doesn't make you an expert. It's not a myth; have you actually understood or considered anything I said?
