Didn't the Man-Hating aspects of Feminism come later though with Gloria Steinam and her ilk? Friedan had expressed distaste for what the Feminist movement has become (Lesbian advocacy).
Speaking from personal experience, man-hating was implicit in the movement. Whipping up womens' resentment with their lives tranlated immediately into a perception of male 'oppression,' true or not. Certainly, some men were guilty of that but all mass movements paint with a broad brush. Friedan established N.O.W. and it was just as man-hating in the beginning as now, just less open about it. As a Communist, Friedan had as one of her major goals the infliction of maximum damage upon the nuclear American family.
To interpret my comments as blaming Friedan alone for all the problems between men and women over the past 45 years would be wrong. Many trends and people came together in a decade or two to cause the paradigm-shift. The Pill, relaxed social mores after WWII, greater international sophistication and interaction, such shams as the Kinsey Report, the lessening of religious influence -- all these things and more were in play.
The sad part is that women of my ex's generation were among the first in U.S. history to be mostly college-educated. I strongly believe matters would have sorted themselves out much more positively and with much greater civility without firebrands like Friedan.
