OK, I am mildly uncomfortable about men boxing. However, I accept that physical aggression is part of being male. And male pugilism has been around at least 2,000 years as a "sport", which seems to support this. I also accept that male boxing has been and is a way to channel young male aggression in structured and controlled boxing clubs, especially for young guys in socially deprived areas to have an alternative to the violence of "gang" culture and, maybe, the chance - however remote - of a career.
But there are physical, physiological and emotional difference between males and females, as well as the level of testosterone (which is linked to inherent male aggression). As to sexism - well I have to put my hands up here. I feel as queasy about this as the prospect of infantrywomen going into battle. But I also accept there were female warriors in the ancient world, including Boadicea (or Boudicca) in Britain. Despite this, however, to me it just seems "wrong". But that is just my personal opinion I don't deny the delight of Nicola Adams at winning Gold and her exuberant smile. I just wish she'd won gold for something else.
