Neither science or the medical industry is with you.
That is where you are 100% wrong. Science and the medical industry are with me.
Used to be that "viability" was the line baby killers wanted to hold. Science and the medical industry are constantly pushing that line earlier and earlier to the point of making the abortion argument based on viability evaporate.
And there is one other very important thing that is not with you;
morality. The justification to kill ones own offspring goes against survival of the species. Fact is the vast majority of abortions are done for convenience, a might poor moral argument to kill babies.
So, to avoid the losing moral argument, you invent this distraction of semantics and pretend the scientific terms of biological development matter at all. They don't.
For me, I would rather my wife have an abortion that her die trying to have the baby.
There are movies where mother's chose to die so their baby could live. That is heroic. Killing your own baby out of convenience is not heroic but contemptible - if anything is.
