Well that's good Job Snow. At least yiure not being a bullish hypocrit. Sounds like, most likely, what you are is uninformed or prolagandized.
There are no and have been no late term abortions except in case of danger to the mother.
Roe gave women till viability. That was fair. It was 21 or 22 weeks. Human germination is 40 week average. So, fetuses can live outside the womb (with advanced medical care) at half bake time, roughly.
Late term basically means within the last trimester. The last 3rd. Doing the math, that's the start of the 27th week.
Let me remind you that almost all of the unpleasantness of pregnancy, the morning sickness, the fatigue, the shakes, the headaches, the hot flashes, the just beinf off kilter all happen in the first trimester. So too, do the development of most of the problems.
Nobody's going through all that just to get to the 36th week and say, "I changed my mind. Abort."
You can't abort a fetus that is viable. You can induce and then put that baby up for adoption if you don't want it. IF you can find a doctor willing to induce early. (We're talking legalities of abortion law here). But good luck there. Most won't until 38 weeks without something else really severe going on, like mom is suicidal. And even then, you're more likely to be institutionalized and put on watch.
Every late term abortions, a super small percentage of abortions, is an emergency. They're tragedies. The fetuses are either already dead or dying or there's just no safe way to deliver without killing the mother. And even then, she's the one who decides who lives and who dies, usually based on already living children. That's as it should be.
