An liberals are not honest about caring. They are arguing because of a few bad cases all abortion should be legal, instead of using this as a reasonable compromise. So long as those are the two choices a lot less humans die if all abortion is banned even if some mothers die as well. (Do not say a fetus isn't a human - that might work for you but it doesn't apply to anyone against abortion and you just look like an idiot for not recognizing what they see as an obvious fact and we get nowhere).

If you want to support a compromise: most of what you need to do is shut up everyone who will only accept their extreme position.
