But there is overwhelming historical (and current) evidence that men are pretty much the sole oppressors of women - and that women have never systemically oppressed men (because they've never had the social, political, or economic clout to do that). Men have been oppressed by men more powerful than they are, and women have been oppressed by those same elites, but also regular men, including the men in their families.
It's a made up story that this isn't the case - one that flies in the face of overwhelming evidence. Men perpetrate over 90% of all violence, including over 90% of all sexual violence (against women, but also against other men). The vast majority of coercive control is perpetrated by men. Up until just a few decades ago, men had a huge number of more rights than women by law. I could go on, and on, and on . . .
If men and women had always been working together we would have never needed the social movements of the 1970s and beyond to demand that open abuse and marginalization of women no longer be tolerated as socially acceptable. That's when the first women's shelters were opened, the first rape crisis centers, and a huge demand for changes to the legal landscape so that women were no longer second-class citizens by law. You're ignoring a huge swath of history trying to make a point that just doesn't hold water.
