BS. Pro-choice people are. They don't consider putting a full term baby up for adoption as a viable choice.
There’s definitely a spectrum. I’ve met women who did this very early in their lives, and who have great emotional reactions to it, and guilt. I’ve also met women who use it as a method of birth control (no joke).
Along those same lines, I’ve fortunately met a lot of parents who put their children foremost in life, and who have been nurturing and loving. That said, there are clearly way too many who are hurtful parents, at best, and too many horrible parents.
