“ In the radical feminist view, the new feminism is not just the revival of a serious political movement for social equality. It is the second wave of the most important revolution in history. Its aim: the overthrow of the oldest, most rigid class/caste system in existence, the class system based on sex - a system consolidated over thousands of years, lending the archetypal male and female roles and undeserved legitimacy and seeming permanence. ”
