Almost. If the woman entered into consensual sex with a man for the purpose of having a baby and there was some form of prior mutual agreement, it could be a different scenario if she then changed her mind, since the father may have some kind of claim on the potential child and if he doesn't, why would he then be responsible for paying for the kid if he has a less than equal say than the mother in whether or not the kid will even be born?
The question then becomes, who owns the unborn, does it own itself at a certain point in time, do the parents have joint ownership until the child becomes capable of fending for itself etc.
I do agree with you though, that ordinarily no person may impose on another without the consent of the other, but if consent WAS given and a being was created, does the father have any rights ?
My this marijuana is good.
