If the biological meaning of life is to replicate, and if beauty is the most important aspect of female mate attraction, and if 20% of any given female population falls well below conventional standards of beauty (or psychological fitness), and hence desirability -- there will always be a hardcore fraction of women susceptible to the anti-social siren call of feminism. Just as a body part cut off from circulation will be beset and consumed by various strains of bacteria, so too will the bottom 20% of the female population be a breeding ground for feminist hatred. For a society to maintain it's upward progress, creative solutions for handling the '20% Problem' will have to be found.
