In medical terms, would this still be called an "abortion", even though, morally speaking, it isn't?  Maybe, I don't know.  Just throwing this out there, to try to explain the reason that this exception is left in many laws.

I have a feeling many people of good will try to come up with these explanations and just presume it's all too complicated for them to understand and of course a woman should be allowed to preserve her own life.

Thanks to the desire to get paid for what they do, the medical field doesn't have a lot of gray areas. Every procedure has a code and there are only a very few that are in the category of abortions. The most common procedures for saving a mother are induced delivery and c-sections. Those certainly wouldn't be confused with abortion. Even chemotherapy, which might harm the unborn child, would never be considered an abortion. If the baby dies, it's almost always secondary and remote from the procedure done to save the mother.

I think "save the life of the mother" is just another tactic of the Left to drum up support for murder. That video I posted deserves to have 10 million views rather than the relatively low attention it has received.

Ah, the Jєω will use both Pro-Life and Pro-Abortion to further whatever real agendas he might have.  Don't worry, they have backup plans wherewith to exterminate the Goy.

Doesn't matter what other plans they have.
Less abortion is good. No abortion is even better. The more laws restricting abortion, the better. Full stop.
What the Jєω tries to do instead is a whole different matter, which will be judged on its own merits.

Let's be realistic. It's more like 99.9%.

How many abortions happen because of incest or rape? A very thin sliver.

How many rapes happen every day? And it's not like the vast majority of them end up abortions. Plenty of women keep the baby or give them up for adoption. Meanwhile, how many abortions happen every day?

and "to save the life of the mother" is a complete crock, so that accounts for exactly 0% of abortions.

No, in over 99% of cases it's because the woman doesn't want her career derailed, her happy life inconvenienced, her education derailed, she broke up with the father already and doesn't want a reminder of him, etc.

I suspect if you outlaw abortion with the usual "exceptions" the rape statistics in this country would skyrocket.

You can slam Trump, and call me wrong, after he signs us up for another war. Not a day before.
Everything short of delivering the goods (i.e., war) is all just bluster and propaganda, meant to deceive the Deep State and play with the Mainstream Media. It's all a diversionary tactic.

Talk to me after we're in another war.

For what it’s worth, I think you are right about this Matthew.
