henry38 - children are not merely the responsibility of their mother. Why do you ignore the voluminous research (much less basic common sense) which shows that children raised in two parent families fare far better than those who do not. Since a child is the product of both an egg AND a sperm, your attitude reflects - in my opinion - just merely more of the problem of sexism that is at the root of these ridiculous characterizations than anything.
When a child is raised it is the responsibility of both parents to shape that child's life in the best way posssible. How, on Earth, can ignore 50% of the equation?
