Dude. You can't go the science route with these people. They don't give a shit about science. They give a shit about what their ideology and peers say is ethical and taking the position most likely to earn them praise from their peers. You have to appeal to their own values if you want to reach them at all. Anything else is going to provoke a sneering contest at best.
That's laughable. It's the left who can't comprehend science when it comes to the medical field. I remember lefties being up in arms because they claimed Republicans were saying it was a baby two weeks before conception. Turns out they couldn't understand how a doctor determined the gestational age of a fetus and that is what the article was about. They still don't like doctors being so cautious about abortions, wanting all the tests done beforehand and all. They think of abortion as a manicure, even late stage abortion. They'd prefer the doctor proceed without any preparation. Heck, they want non-physicians to take over abortion procedures so we can have even more of them. And forget that safety shit, like being a reasonable distance from a hospital when something goes wrong. I posted a thread not long ago regarding the lack of oversight and inspections of abortion clinics. The left wanted legal abortion to end the back alley abortions and now they pretty much want to go back to that.
Try messing with an eagle's egg and you'll be in big trouble. It's just an egg, a nothing, right? But of course we know that destroying it means ultimately destroying an eagle.
There are too damn many abortions and the left prefers that over people being responsible. It gets worse every year.
