Feminists support women, period. They can more or less do as they wish and their behaviour will be condoned as an empowered act of liberation from the patriarchy or male oppression.
Frankly I'm tired of feminism and wish we could abolish it and enforce equalism instead. Once we stop drawing on all these gender separations, we can start to explore true equality between the sexes. Yes we have biological distinctions, but they aren't the problem. These socially constructed gender separations are what's driving the conflict between the sexes.
