Searching Babe Didrikson Zaharias led me to this page from feministblogs.org.
"First of all, we could stop sex segregating sports. Little boys and girls play together when they are younger, but by the time they reach junior high school they are locked into rigidly segregated sports worlds. Many would argue that women are biologically unable to compete with men, but that’s a load of bull. When women are encouraged to compete and socialized into the rigors of training to be competitive athletes, they can compete at the same level as men. Basketball is basketball, and track is track"
Is this a common belief amongst feminists or just the extreme fringes?
Utter bilge. Our Australian women's basketball team is one or two in the world, yet cannot beat a state junior men's team.
