Wow, actually getting my teeth into the historical reasons, the psychological reasons and the biological reasons of why we still have elements of a patriachy, why it existed in the first place etc. It's really interesting!
Sorry. History buff here!
If I correctly have it, all you ladies are really wanting the world to be egalitarian - equal rights for all. Apparently, if you go back 6000 years or so the world was that way! And even in (comparatively) more recent times, the ancient Egyptians had a much more egalitarian view of the world. In our modern world, you can blame the Greeks a fair bit for the spread of patriarchy. Greeks hey! If they aren't bankrupting the world they're spreading male rule!
Technically, Patriarchy is "the rule of the Father," so it actually more refers to the power of older men over women, younger men and children. Of course, younger men in this society can inherit that same power in time. Apparently, those who are raised outside of the normal patriarchal family unit, like myself, rebel more strongly against it.
I'm all curious now. Why, after 6000 years, has it only been this last century that society has started to change? Need to do more research!
