Female socialisation means: put others first, serve others first, mummy eats last and least after everyone else's needs are met, and good women do this without mentioning or complaining about it .
It's also instinct. Having and raising children does make you selfless. As a grandmother, presently living door-on-door with my daughter who has a 2 year old, I observe this every day. There is no way she could raise that little child without endless understanding, putting the child first, putting her own desires and needs in second place.
Being selfless is not in itself a bad thing, or a weak thing; in fact, I believe that being selfless ie not putting your own needs first activates a deeper strength and resilience that actually has more staying power, more courage, fortitude, determination, tenacity, than all the ego-driven power-trips in the world. No narcissist can hold up against someone like that. It comes from underneath; I'd call it heart-power, though I know even that sounds soppy to some people, when it isn't. It's quite the opposite. Never underestimate that instinct: to care for others weaker than ourselves.
We should not have to do this for men. We should not have to lower ourselves to men. It's why hand-on fatherhood is so good for men, in that it teaches them selflessness, to be good, strong men.
That ability to be truly selfless really only applies, and should apply, in dealing with young children. It's why it's often grandmothers (freed from having to please males, to catch a mate) can see through the ego-fuelled games and tantrums of men. It's why we recognise narcissism when it rears its ugly head and are willing to chop that head off, disobey it. It's why, once we have uncovered that latent power (and you don't have to be an actual mother to feel it) there is no stopping us.
It's no coincidence that the pushback is coming from those who would do anything to protect children, and other women, even at the cost of their own safety and comfort, a la Posie.
This was a bit rambling, a bit of a rant. Sorry.
