Girls have always played contact sport. In particular hockey! When I was at school in the 70s we (ie the rugby team) always used to play the girls at hockey during the last week of term and we'd get thumped, in more than once way. They could wield the sticks like demons. Likewise they commonly compete at the likes of judo, taekwondo etc. There is no valid argument for excluding them from boxing! The argument "I don't approve" just isn't a valid argument. As I said whether a sport should or shouldn't be an Olympic sport is of course debateable - but we shouldn't be prejudiced against anyone. Even the likes of saudi Arabia are wakening up to that!
