Gender Relations
The passive woman is still traditionally attractive. The passive woman is the instinctual role ground in maternalism. Women are maternal instinctually they desire to be mothers and to mother others. This instinct explains why women are often willing to date men with tremendous flaws, as it will give them something to mother.
On the other hand, men are instinctually protectors. They want to feel needed as a provider and a protector. As such they find a female's maternal nature very attractive, because by its very nature she will need protection while she provides for their children. Therefore, the more a woman needs protection the more attractive she will be.
Since, instincts do not change or are not ignored easily this trend of the passive women being attractive is not something that is going to go away in a couple of generations if ever. The truth of the validity of these instincts is that they have transcended space and time to be present in almost every known society.
So, what you really have is a system of co-dependence. Each feel the other would be lost and helpless without the other. The woman feels the man needs her guidance and her child rearing expertise. The man on the other hand feels that she could not survive without his protection and support.
The 21 st century is going to be a frustrating place for the traditional male. Women no longer need depend on man. Women can now legally provide for themselves and are legally protected. The fact men cannot bear children this puts them in a particularly difficult position of almost being a third wheel. As opposed to women are not facing any threat to their maternal roles as child bearers. Bottom line, I believe only the strongest willed men could transcend their own instincts to see an Independent woman as their “Madonna”.
