Telegraph article here quoting the head of Latymer Upper School, saying that girls in co-ed schools aren't put off playing sport by their male peers. 
Leaving aside that most children aren't rowing or playing cricket at their school, can I just point out that he clearly has zero appreciation of what playing sport as a teenage girl is really like? Boobs developing and being very painful (or no boobs developing, and being very obviously lacking in unflattering PE kit). Wobbly legs suddenly exposed in short PE skirts. Always having to play the boys sports (like basketball) rather than the girls sport (like netball), when playing together. Being beaten by most boys in most sports, because even scrawny boys who haven't yet had their growth spurt tend to be stronger and faster than teenage girls.
I'm hoping that he thinks he is genuinely sticking up for girls, and pointing out that it isn't all about impressing the boys, but it jsut smacks of He Doesn't Get It, doesn't it?
