By pushing this concept of sameness (men and women having the same role or identical roles) as "equality" it has diminished marriage and the way men and women value EACH other. Both men and women are worse off today, but women are more worse off because they get stuck with the reproductive burden without any of the previous benefits. Men are no longer valued for their role, and women are no longer valued for their role. No one knows what to do. Everyone suffers. Everyone is in it alone.
I don't think anyone is saying that a man or woman should be viewed only as a father or mother.
