To Elba: you're right, women can have a heavy weight... but that was just an example: every power-oriented sport has differente leagues for men and women, and I don' really think for discrimination reasons!
To Dixie: I can't see any king of discrimination, here. On a phisical basis, men and women ARE different, so it would be wrong to let them compete together when phisical power is the main issue.
I would be pleased, however, to see men and woman together in other kinds of sport, e.g. shooting with bow and arrow, rifle, gun, or any other sport where phisical power is not significant.
