"Again, in a practical world how could we enforce the idea that a man who didn’t really want a child wasn’t responsible for the child? How many deadbeat dads would step forward with their reluctance, their ambivalence, as a way to worm their way out of responsibility? It is very hard to see how this could be written into law, the didn’t-want-him argument, without wide-scale abuse and harm to the children involved. On the other hand, it might be reasonable to recognize that there is a certain amount of unfairness at play. There is the possibility that a woman who has a baby against a man’s will should in some moral, if not legal universe, claim financial responsibility for that child."
Perhaps we need to consider for a moment that contraception methods are not a guarantee against conception.
