Feminism actively encourages women to waste their youth hoe-ing around or in school. Far FAR too many women do not recognize the value of their youth until its far too late. Because male attention comes to them early in their lives without them having to really work for it, too many of them take it for granted. They start thinking they really are that sexy or fun to be with and that "there will always be another" when in reality that just ain't so. In the old days, their mothers, grandmothers, aunts, etc used to set them straight...telling them not to waste their youth, that they needed to find a good man, that they need to put more emphasis on finding a man who would be a good and loyal partner was vastly more important than find one who was 6 feet tall or finding one who was responsible was more important than finding one who got a piece of paper from a university.
That's gone now. Now their influences are Hollywood, TV programs, things they read in places like Vogue magazine, etc and those influences are steeped in feminism. Many do not realize they've been sold on a pack of lies that will lead to their unhappiness until they find themselves in their early to mid 30s and discover that men just aren't pursuing them anymore...ie that they're not that sexy or fun to be with (any more). Then they get very bitter and angry about it. Usually that's directed at all men in general. It should be directed at the people who told them those self destructive feminist lies in the first place.
Whenever this topic comes up, men completely ignore the influence of No-Fault Divorce, which allowed men to trade in their aging housewives for younger models. Do you remember the phrase “Trophy Wife?” Men have contributed to this greatly. It wasn’t just feminism that convinced women to go out and earn their own keep. It was fear that they’d be discarded once they were middle-aged.
