You have a point if you are assuming
that feminism's sole goal was to access
society as is. And in part that was feminism's
goal, but it actually has made a more profound
calling, which is to alter society to the
extent that value systems change and success
isn't based solely on how well we acclimate
to the status quo.
Also, even as is, while
women might have accessed those worlds
they aren't approaching equality in them,
and too few men have taken on "female" responsibilities.
Just read Ask Amy and you will see
that there is a need for resources.
