i believe that we have socially evolved, but not yet physically (or nuerologically).
we didn't have close to enough time to evolve into the enviroment we're currently in. eventually, people who think like you guys think i think will be weeded out, but not for hundreds of thousands of years. it takes a species our size that long.
the intellectual demanded enviroment, which i talked about earlier, where men and women are at a level playing field, is very recent. before the intellectual society, dominance depended on physical attributes, which put men at an advantage in getting food, building houses, and obtaining all kinds of resources. so it was beneficial for women to look for men who display traits of dominance.
homo sapiens have been living in that society for 1/2 million yrs. different homos have been around for 2-3 million yrs before that. this is where our instincts came from.
our brains are still configured to live in the primitive society. for example, humans can deal with numbers in millions, but we can't conceptualize it. we can conceptualize what 10 or 20 apples are, but no one can conceptualize (or picture) what 1 millions apples is.
the configuration or our brains came from a time when we didn't need to. same with gender roles. our instincts may no longer needed, but written history has shown that humans are yet to not be subjected to their influence.
anyone listen to rap music? hear how men talk about women? politically, it's degrading to women. but so is the way the male rabbit treats the female. so, we haven't completely--or even a little bit--evolved yet and we all got a little bit of that rabbit in us.
