It's not as easy, but if you never wanted to have that baby you can give it up the day it's born, before any real bonding happens.
Is it your argument that women having a stronger attachment to a newborn is a bias against them? Because I was only trying to argue that there was less bias than EGreg said. If she decides she wants the baby then it doesn't seem like a negative to me.
Edit: Oh, I'm a dumbass. I didn't make it clear that the 'giving up the child' was only in response to the pregnancy scenario. That's because once both parents are raising the kid, after a breakup both or either of them would continue raising it.
What? Nursing doesn't last that long, and 'lack of sleep' is part of rearing and not forced on the woman.
>The man can just leave. The pregnant woman can't.
She can give the child up for adoption just as easily as the man can leave the relationship. And rearing is the vast majority of the effort.
Yes women have to do more, but the difference is not nearly as much as you're arguing.
