The concept of yin-yang exists for a reason -- things need opposites to balance them out. Feminism argues for both men and women being yangs, with nobody being a yin. Yes, this is more "equal", but it's not harmonious. It's like putting all the weight on one side of the scale; it just doesn't work.

Worse, feminism also argues for men and women switching positions of yin and yang: Turning men into yin and women into yang. Evolutionarily speaking, this is wrong as well.

Women are not "below" us. They are not "inferior" to us. They are, however, indisputably different than us. We are programmed to be the dominant gender, as they are to be the submissive gender.

Balance. Harmony. Equilibrium. This is what we stand for.
