The professional literature and parenting books talk about this guy. In reality he's hard to find. But he is supposed to be the father of the future. He shows tenderness, expresses emotions, nurtures, is a mother's colleague changing diapers. There are some good aspects, but there is very little male about this way of thinking about fatherhood.
Masculinity is viewed as a problem to overcome.
You can see the antipathy in the recommendations that we resocialize little boys, change their toys, rewrite their books. We did 250 interviews with married fathers. You get a much better definition of what fathers should be from them than from the literature. These guys do not believe they are superfluous. They have a rich, strong definition of themselves, and their wives agree.
