The problem with feminism, as with any ideology, is that it causes its followers to view the world through a pair of goggles. Feminism happens also to be a very narrow ideology, such that the vision becomes very narrow. The hole world and all its moments centre on your gender.

Instead of focusing on the real issue, which is the conditions for individuality, feminism tries to reinvent the world in which there exists some sort of vicious conspiracy that aims to humiliate and control some sort of 'womankind'. It's a conspiracy theory light that asks its brave knights to charge against an invisible and non-existant enemy entity ('patriarchy', or whatever; put a name on the dragon).

Feminism is self-defeating because it battles individualism by splitting the humans into two camps, femmes and hommes (an inevitable consequense of a monotonous focus on gender). This while the very core of the problem is that females (as males) may be judged by gender rather than individual capacities.
