In the cases of rape and incest, a horrid wrong has been done to the woman involved
False. In cases of rape, a horrid wrong has been done to the woman. She could be a willing partner in the incest.
having to carry and bear (and then support) the resultant child only furthers the wrong done against her.
So what happens when the woman uses contraception, but it fails? She has done nothing wrong, but must bear a huge burden. What about cases of disability? Or do you think that women should not be engaging in sex at all?
Pragmatism is always an empty position. Pragmatic means practical
And that's my point. The "No abortions except in cases of .." is a pragmatic position, because it recognizes that the majority will not accept a simple "No abortions" rule.
