Where's your proof? Counter-examples are easy to find (Look at the Whedon family for example), so you better start shifting your explanation.
And how the hell has the pendulum swung too far? I'll quote OSX's dictionary. Feminism is: the advocacy of women's rights on the grounds of political, social, and economic equality to men.
As far as i'm aware, we still live in an unequal society. Men make more money than women. Women still face discrimination in the work place. Women are not anywhere close to being proportionally represented in government.
So tell me again, where does the pendulum stand?
