@Joseph MaynorYin gives form to force, its the way every human being enters this realm. Yin is constantly restricting, refining, forming the formless energy, the pure potential.
But like you said, every human being has both masculine and feminine aspects. A woman who acts with agency is not simply appropriating male behavior. Through most of recorded history women have been scapegoats for what men define as "evil", from the garden of eden, to mara tempting buddha with beatiful women to keep him from becoming enlightened. Desire of women hindering one from transcending the wheel of samsara. The womans knowledge being the reason for the fall of "man". Its men fearing their own desire, limitations, and what they cannot control, and what they cannot do, which is create life(form).
