You GOT it kiddo. Most abortions are done under coercion or pressure. In fact, the very reality that abortions exist acts as a coercion of sorts because many of the woman’s friends, co-workers and so on will suggest it even if she has no desire to do it at all. It’s very complicated.
Keeping abortions "safe" and "legal" intensifies this pressure by several orders of magnitude. Women who were blithely unconcerned about abortion before they became pregnant, suddenly find themselves facing an internal conflict they never dreamed possible, as the truth dawns that the issue is about ending the life of another person. But usually, she is the first and often the only one in her circle to realize this. All the rest, to whom the "fetus" is either an unreality or a conveniently disposable inconvenience, are lined up on the side of the "abort" option, with the law on their side. This leaves the new mother in the opposite corner, scared and confused by the intensity of the apprehensions she had no warning were coming, facing this entire phalanx singlehanded. Small wonder many just give up and try to numb themselves "until it's over", hoping the problem will eventually go away.
But it doesn't. Abortion makes the problem worse, while simultaneously slamming the door on the best healing opportunity.
