It doesn't have to be "murder" for it to be illegal. It's not murder to kill a dog, but it is a crime.
The only solution to the abortion issue, as a practical matter, is compromise, and until we start discussing this pragmatically, and stop arguing unwinnable points, like "is it murder or is it not murder", then we will never settle it.
Abortion should be allowed on demand early on, and then after a certain point the State has an interest in preserving the life of the fetus (whether killing it would be murder or not), and there should be protection for women who need an abortion to save their life or the like. Where the lines are drawn should be what the political discussion is about. The reason why it's not about that in the US, is because our "narratives" have been so polarized, that we are incapable of discussing it sensibly. In Europe, they have abortions generally, but there are limits and there are rules. In some countries, they need doctor approvals (like in the UK) and they need "reasons" and they can only be performed in hospitals, and they have more restrictions as the weeks go by during pregnancies, and yet they seem to be fine with it.
Why is it that in the US the discussion has to be "it's an absolute righto have an abortion at any time for any reason or no reason at all" on the one hand, and "never can there be an abortion after conception" on the other?
Shit - I'm apparently a "right winger" here and yet I'm like - for sure, morning after pills, abortion pills, etc.., are fine, and on demand through 12 weeks sounds prett fair. And, then having good reasons after 12 weeks sounds pretty fair, too. I have daughters, and if some asshat rapes one and impregnates her, legal or not legal, I'm not making her suffer through a pregnanch caused by a rape, for example. And, if she just made a mistake and can come to me and say "dad, I made a mistake" then she should be able to tell me that early, so that we can go together and get it taken care of as early as possible. It's not a "baby" at 6 weeks. It's not "clump of cells" at 22 weeks. The discussion needs to recognize this.
