I personally agree that boys are bigger and stronger than girls and having them compete with girls is unfair.
However, if our nation has decided that women are big and strong enough to fight against enemy males, in combat, then they certainly should have no problem facing males on the volleyball court.
Did you notice in the article the part that says the girls regulation hoop is one foot lower than the boys?
Apparently, there IS a problem, not that the feminists want us to notice. The article points out not only the lower hoop height regulation for girls, but also that boys play harder and more intensely than the girls, so get more play -and thereby not allowing some of the girls to get as much time off the bench. Unfair!
