That’s an interesting perspective. My own anecdotal experience from talking with women about this issue is that those who have an abortion(s) tend to be reinforced in their pro choice stance, and those who have an unplanned baby tend to be reinforced in their pro life stance. The popular culture does backflips to tell young women that having an abortion is just fine. The living, breathing baby tells a young mother that she did the right thing. One way requires massive amounts of conditioning from the outside world, the other simply requires nature.
My own anecdotal experience of women who have had unplanned babies is the same as yours, but I have met many women who have had abortions and regretted their choice. Even if they were "pro-choice" before their abortion, having aborted a child and faced the reality of what they did made them change their minds or at least feel very burdened with guilt by their decision. Having been very active in the pro-life community for years, I was surprised to find out that many of those involved in the movement had experienced abortions and now regretted their decisions. Of course there were the hardcore abortion advocates who continually justified their decisions, but most women are not proud of their decisions to abort their children. Deep down they know the truth. For a very large percentage, the free “choice” was not truly free. They felt pressured into it by boyfriends, husbands, parents, and abortion providers.
I guess once you’ve devolved down to hell because you’ve aborted a soul before it even had the chance to agree or disagree, the best tactic is to fully embrace the evil lest you displease your new dark master.
