The old rules of ladies first, never hit a woman, etc were based on a social contract. That social contract is now dead. Women act independently and don't need men. Hence they abandoned their side of the social contract and so did men (at least the ones who know whats going on).
The problem still, though, is something that I have stated before. Read it very carefully: Women want equality when it works in their interests, and they don't want equality (i.e. they want the old style chivalry and special treatment) when equality does not work in their interests. You see, wanting equality has two sides to it. In some cases it works in your favour, but sometimes it doesn't. Women pick and choose when they want equality. At work and education, women are capitalists. In their social life, they are socialists.
The worrying thing is though, men are completely oblivious to this. They do not see through this game. They give women exactly what women want, not realizing that they are getting played by women. The evidence of this is all over the place. Why is it that even though women can make money, men still have to pay the bills while women can spend money as they like. Why so many men continue to act chivlariously and like white knights, despite those things contradicting with equality (while at the same thing they also think that women are equal). etc, etc.
