@akargeThat's so dumb of course, but I have to say makes sense if you count life from inception. Every such procedure is a mass murder in such a paradigm.
But it helps to so many couples have children who otherwise couldn't for all sorts of reasons.
Like I know a couple who tried for a child for years without success although both were healthy. Then they discovered her irregular, painful and heavy menstruations weren't menstruations, those were miscarriages. Dozens by then, possibly. Rhesus factor mismatch, she was negative, he positive, and their chance to randomly get a negative child was somehow very small, but she would drop out a positive fetus. So they did in-vitro with sorting. Two very beautiful fraternal twin girls are doing their master's degrees now. And guess what, they get two more completely natural children afterwards. Because after first successful pregnancy she now can have rhesus positive children too.
