No, I do agree with you that arguing for total abortion to term on demand is bad tactics and will not fly.
I do want, though, to call attention again to the very high maternal morbidity and mortality rates in the US and to the lack of national healthcare. It is a fact that pregnancy in the US is risky -- you cannot look at the situation here and say there is not the slightest indication of risk simply by the fact of pregnancy. Even with the most affordable health insurance, one still has to meet a $6000 deductible before the insurance pays one dime. That makes getting maternity care very difficult, which is a prime cause of risk in pregnancy.
But I'm not at all saying others want women to die. I'm speaking from a more philosophical level and peering into both the past and the future.
Currently, rightwingers in the US are in great distress over falling birth rates among citizens. We've had similar issues in our past over controlling who has babies, and when. US history with regard to women and pregnancy is fairly ugly, including the forced pregnancies and trial for murder after stillbirth our English foremothers faced, most of whom were not Puritans but prostitutes and thieves who chose indentured servitude in America rather than death at the gallows. I haven't even touched on the horrors of forced pregnancy black women have faced in the US, and then the horrors of forced sterilisation.
I think that American women citizens need to know explicitly that the state regards her pregnancy as a time in her life when she gives up certain rights in favor of the rights of another. I want that stated clearly, not blurred into soft focus.
After all, it is on that premise that the state imprisons women who endanger a pregnancy by using drugs or alcohol. It is on that premise that women who miscarry are investigated for murder, and at times jailed while that investigation proceeds. These are things happening right now, in the US.
The pro-life position removes rights from women in favor of another. That IS what you're in favor of. People are simply arguing about the date upon which that happens.
