So what should women's responsibility, rightly assigned, look like?
A woman’s responsibility should be the same as the man’s responsibility. If two people co-create a child, BOTH are responsible for the child.
Jointly, BOTH can decide to give up the child for adoption. But if one parent decides to keep and raise the child, then the other parent has to contribute as well.
The whole focus should be on what is best for the CHILD, not how much responsibility one parent can foist off on the other parent.
Bickering about who is responsible for the child being created is beside the point and is only an exercise in trying to absolve one parent or the other from responsibility ... the only outcome of that is the child will bear the full consequences, not the adults.
After a child has been created, the parents have forfeited their unilateral decision making opportunities. Each adults’ personal decisions for themselves become secondary to the welfare of the child from there on out.
If society supported and enforced such a position we would never have had child abandonment in the past nor abortion today.
