Marriage has become a shaky foundation for parenthood of late. When the father and role model of a young boy or girl, can be ostracized from the family on the whim of the mother, and many of the laws of the land will fall in her favor, there is a fundamental problem with fatherhood and the value that society gives it.
Men have always been disposable. In war, and in industry for example. It has just become more prevalent in these modern times for them to be disposed of in family life too.
It doesn't matter how committed you might be to fatherhood, when fatherhood can be taken away from you, and our culture looks upon that event with a cold heart. He's just another man. No good. Get rid of him.
There sure are a lot of examples of situations like that in our society.
