I feel like I'm repeating myself, but...
No one should make choices that put them in a situation they do not want to be in, unless they have a surefire way of getting out of that situation.
Noone should, but they do. So, once you're faced with the reality of a woman who has previously had 3/4/5 abortions, however many you feel are acceptable, but is pregnant again and wants an abortion, which you now feel is a 'lifestyle choice' and unacceptable, the public will have to either 'pick up the bill' for the abortion, or 'pick up the bill' for the pregnancy and birth.
The pregnancy and birth is more expensive than the abortion, so don't you think the public would rather pick up the bill for the abortion?
There is a whole other discussion to be had about the best way to enable a woman to avoid needing multiple abortions, but you keep coming back to the outrage that the public has to pay for them, so I wanted to address that point.
