I said a man is ethically responsible for half of the cost of an abortion, not completely free to wash his hands.
This is the difference between getting off free and getting off cheap. You're splitting hairs.
And in a place like Canada, where abortion is funded by our public health care system, you
are talking about letting the man off the hook completely.
Retaining the child is completely the choice of the woman and requires more medical supervision than a first or second trimester abortion (even if it's natural and not a C-section). She can use that money however she wishes, but after that, it's her responsibility. He didn't want the child. She did. If she didn't, she would have opted for an abortion or adoption.
And if the man didn't want a child, he would have opted for contraception. How is there any ethical difference at all? I've asked you this before, but AFAICT, you never really addressed it.
I kind of see what you're getting at here, but I think you're being wrong-headed: mitigation of damages is the legal principle that says that a person who has been wronged has an obligation act in a reasonable way to limit the amount of damages that occur... for instance, if you discover that your ceiling is dripping water because of a problem with the plumbing of the apartment above, you still have to do things like let the superintendent know, move your valuables out of the way, and put a bucket under the drip. If you don't do these things, then the guy upstairs is still only liable for the amount that would have been damaged if you had acted reasonably.
It seems to me that the implicit message in your argument is that abortion is the "reasonable" thing to do in the case of a pregnancy that the man doesn't want... or rather, that if the man doesn't want the pregnancy, it's unreasonable for the woman not to get an abortion. Just as we consider you to be acting unreasonably if you don't move your antique whatsit up off the floor before the water dripping from upstairs hits it, you're implying that we should consider a woman to be acting unreasonably if she doesn't get an abortion.
Like I said, I think this is wrong-headed. I think both having an abortion and not having one are reasonable approaches to the situation, and therefore neither one should be used as some sort of trigger to end the man's responsibility.
If you need to rely on an unwilling father to finance a child, you shouldn't have a child.
And if you don't want a kid but need to rely on the woman to make sure that contraception is taken care of, then you shouldn't be having sex.
Single parenthood is more often than not a bane on society. The current state of affairs just subsidizes a huge bureaucratic machine that targets men and lets women off the hook. Refer back to my two posts on how women get away with child support. There's nothing immoral about abortion.
The issue isn't with the morality of abortion itself; the issue is with the morality of creating a financial penalty to push women into abortion.
