That's assuming they don't know. My point is that they do know, and they may say they didn't know because society is not willing to accept women saying "I'm done. No children for me." Career is the only excuse others in society will accept for a woman to not be actively working toward raising children.
Don't be surprised that children, male or female, who were traumatized within their own family growing up forgo families of their own. I know quite a few women, many who suffered through childhood trauma, who knew at a very young age that they didn't want to have children. Maybe it was a defense mechanism, maybe it's a deep distrust of the institution of marriage and the family, but they knew they wanted no part of it.
They're not fools chasing a career. "My career" is what they tell others in public. In private they'll share that they don't want children and every time they hear the "but children are...", "how could you not...", "everyone has issues...", it angers them because it denies what they've been through. These women found it better just to say, "Career now. Kids someday." to avoid conflict and judgement from intrusive outsiders.
Often, the worst flak they get are from other women who don't want to admit they didn't have the strength to not have children. The other women were afraid of being alone. They had children to "fix" their marriage. They hoped it would get better over time but it didn't, and now they have to live with guilt of screwing up their own kids.
I haven’t discounted anything. Nothing changes that the value of males and females come from their ability to propagate the species, because it keeps their civilization alive. People who dont contribute to that, which includes myself, do not contribute to keeping civilization alive. It makes them disposable in their value, moreso than people who have children. That is just a reality.
It is also a reality than women’s main roles are nurturers and men’s main roles are providers. That is also a reality. Men don’t typically do nurturing well and women typically dont do providing well. We were created for different roles and it is the confusion of this that is causing the breakdown of society.
When women chase careers in their twenties, they ate doing themselves a disservice because they are reducing their ability to be the nurtures they are meant to be. Women who claim to not want children often find themselves realizing too late that they were lying to themselves, but they now have to live with the consequences of what they did to themselves.
It is not a strength of character for a women to deny themselves children. That is simply the words of somebody who bought into feminism.
