If you read the article, he was held responsible, but I agree with you. Seems rather harsh to hold a 14 year old male statuary rape victim responsible for a six year old daughter he didn't even know about.
I agree, too. They held him responsible even though the female partner was older and exploited him because in their first encounters he consented, though he was too young.
I frankly don't have the same attitude toward child support as lots of people.
I think that if both people want to continue the pregnancy, both should be equally responsible, which would mean the man would pay half the pregnancy-related, childbirth, and nursing-related costs as well as child support. If neither wants to continue the pregnancy, the man would pay half the abortion-related expenses.
If he wants the continuation and she doesn't, or she wants the continuation and he doesn't, she should have the right to decide because it is her body. In both cases, he would technically owe her half of the lowest possible cost incurred, which would be equal to half of the expenses that would be incurred by abortion if she had one. However, if she alone wants the continuation, I think he should be allowed a paper abortion, giving up all parental rights in exchanged for giving up a responsibility for child support.
Of course, the reasons we do not have such a system are:
1) women fear that if men have to take responsibility for any expense during the pregnancy/childbirth, they will demand to be part of the choice of whether or not to continue a pregnancy, and
2) the government wants to get the man to pay half of the child support so that it does not have to when the woman has a low-paying job or no job.
