Some people believe that the rights should be circumstantial. For example..
Say the father does not want to have a child, yet the mother does. So, they have sex. That's when Zorn's point comes in. A woman can easily get pregnant and blame it on the person they are seeing. Then, she'd have a child, and bam. Poor guy is paying child support. And all the woman has to do is go to a sperm bank, or do whatever they want to do to get pregnant
(i.e. she can say she's on the pill so there's no need for a condom, and blah blah blah).
But what I believe, is that a woman does have all the rights to do with their child. In reality, men are just tools for reproduction (not to put down my own kind). I believe if a woman wants to have a kid, she can. If she doesn't, then she does't. She's the one that has to deal with everything that comes along with having a baby. Therefore, if the man just ups and leaves, then she SHOULD get on his ass for child support. I mean, men just denying their actions.. That's just being an irresposible person. And what people have to realize is that everything they do, they're responsible for it. Doesn't matter if they don't want to be a parent.. They're the one taking the risk. And aren't always beneficial.
Don't know if this is what you were looking for..
But I figured I'd throw my opinion out there.
