Killing.
That's the word which is at the heart of the abortion debate.
No matter how hard you try to dehumanise the unborn baby, the disabled person, the Jew, the negro slave you call chattel, the Downs Syndrome sufferer, the quadriplegic, the Covid-19 patient on life support, the parasite....
there is a clear medically - scientifically - defined line in the sand that is crossed when you "kill" a living human.
You have no obligation to keep any of those alive by being forced to donate the use of your organs against your will. Refusing to donte the use of your organs may result in them dying. You may even choose to call that “killing.”
Nevertheless, you are not obliged to donate your body to anyone for use of your blood, tissue or organs.
I can see why you would keep dodging this fact, and instead choose to talk about emotional words like “killing” and “baby” in the hopes that they will paper over your desired to take ownership of other people’s bodies and direct their use against their will.
This isn't so much a fact as an irrelevant analogy. What makes it irrelevant is the lack of choice or responsibility on the part of the donor. Expecting Joe to donate an organ to Bill, just because Bill needs one, is morally very different from expecting Joe to donate if he'd chosen something that resulted in Bill's organ failure. But that never happens. It's so unlikely that the same person both caused the organ failure and is the best organ donor that it's probably never happened since organ transplants became possible.
That's really different from having sex and making a baby. That happens all the time.
A better analogy is this. A motorist who hits a pedestrian with her car, causing life threatening injuries. It doesn't matter where she was driving or why. It doesn't matter if she was being careful. When she put her car in gear, she was taking responsibility for possible outcomes, even remote possibilities for which she wasn't prepared. She could have stayed home or found other transportation, but she chose to drive.
There is one huge difference. Nobody wants the motorist to personally provide emergency, medical, job coverage or any such thing. Other people are far better trained and equipped to do it. Motorist is just expected to pay. But paying is a moral obligation. If she doesn't have insurance, her assets will be seized and wages garnished, even if that's terribly inconvenient and burdensome. The moral calculus here isn't hard to understand.
And if she decides that taking responsibility is just too inconvenient and burdensome, so drives away leaving the pedestrian to die on the pavement, that's another whole moral choice. I'm sure you understand that one.
