It is unfair when we do not force the same on the mother.
We do. Woman are just as responsible for the children they bear as the father is. This begins the same time the father's obligaions begin: birth.
Most people who pay child support earn that money through the use of their body.
True, but that isn't required of them. Pregnancy does require the use of the woman's body. There is no other option.
But I agree there is a difference here, but that difference results in the mother being able to actually terminate the pregnancy, while the father is only able to terminate his responsibility. He gets less power to terminate, but he still gets some.
She gets the "power" because it's her body doing the work. His isn't.
You just appealed to the law ("legal obligation"). If you have nothing better to defend the law than circular reasoning... normally that is a bad sign.
I'm not defending the law so much as stating that it exists. If you want to change it, then present a legal argument for doing so. All you've said so far is that it's unfair, but that is false since both mother and father have obligations to the child after it's born.
You have not given any reason why a father's parental rights should extend to the mother, who is not his child.
Got bigger fish (injustices) to fry (fix) first.
Your call, of course. It'd be a hard battle anyway, since some men have been trying for centuries to shirk their fatherly duties, to no avail.
But not fairly applied as the law can allow (not does allow).
I disagree. Both mother and father have rights and obligations toward their children. After birth.
The point being, if the woman had an obligation to be a care taker, then she has given up the right to her body by taking on that obligation.
You base that on what principle of law, exactly? Far as I can tell, this is just your opinion, an opinion no woman is required to obey.
My point stands you force the obligation on the man but not the woman, which even considering the differences in what the obligation entails, is still inconsistent.
Both woman and man have obligations as caregivers. Those obligations begin when the child is born. Not before.
Where did I mention custody in that part of it?
Caretaking = custody, does it not? The primary caretaker is the one who has custody of the child.
