It's one of the reasons I hate "feminism". People see stuff like the Womyn's Music Festival and think that's what feminism is - excluding others and pushing that 'womyn' (I really hate that term) are somehow *better* than others. By pushing the idea that "womyn" are somehow better, I think "feminists" are actually hurting their cause more than helping it.
IMHO, feminism isn't about being *better*. Feminism is about doing anything men can, being paid accordingly, and having the same opportunities as men. In other words, equality. Women should be able to, and encouraged, to do whatever they want. There should be no "masculine" or "feminine" jobs or activities. There also shouldn't be any hair-splitting on who is a woman either. We're all different after all - that's what makes us strong.
