Because you seem to think it's the history of humanity and it isn't - and your wiki in many ways confirms this. I say 6-9k years because it obviously arose in different places at different times over thousands of years - not actually in dispute according to your wiki. But as I've already said to you more than once, the concept of fatherhood or even male-led societies is not what the word patriarchy means from a sociological perspective. Those are parts of the equation, but far from the total of what makes for patriarchy. You don’t seem to grasp this and you haven't actually presented anything that indicates differently. In fact, you haven't presented anything meaningful or substantive about any of this other than one wiki which mostly supports what I've said.
In your original comment, you said this: "Genetically and as a result culturally up until recent history, evolution selected for patriarchy in almost all places." But this isn't remotely even beginning to be true -it's a frankly absurdly ascientific thing to say. It is only in recent history that culturally patriarchy has become dominant — but not for evolutionary reasons. And to be honest, I have no idea why you would even bring that up as a comment on a story about how your gender does not determine your aptitudes or capabilities. One has nothing really to do with the other. And all of that absolutely has nothing to do with a return to egalitarianism - something that I never once expressed an opinion about in this OP.
Since you can't actually hold a coherent conversation, I think we are about done here. Your absolute confidence in your convoluted and unsupported notions doesn't interest me in the slightest.
