It's not about regretting abortions. It's about people who said "abortion for me, not for thee."
“I have done several abortions on women who have regularly picketed my clinics, including a 16 year old schoolgirl who came back to picket the day after her abortion, about three years ago. During her whole stay at the clinic, we felt that she was not quite right, but there were no real warning bells. She insisted that the abortion was her idea and assured us that all was OK. She went through the procedure very smoothly and was discharged with no problems. A quite routine operation. Next morning she was with her mother and several school mates in front of the clinic with the usual anti posters and chants. It appears that she got the abortion she needed and still displayed the appropriate anti views expected of her by her parents, teachers, and peers.” (Physician, Australia)
“I’ve had several cases over the years in which the anti-abortion patient had rationalized in one way or another that her case was the only exception, but the one that really made an impression was the college senior who was the president of her campus Right-to-Life organization, meaning that she had worked very hard in that organization for several years. As I was completing her procedure, I asked what she planned to do about her high office in the RTL organization. Her response was a wide-eyed, ‘You’re not going to tell them, are you!?’ When assured that I was not, she breathed a sigh of relief, explaining how important that position was to her and how she wouldn’t want this to interfere with it.” (Physician, Texas)
“We too have seen our share of anti-choice women, ones the counselors usually grit their teeth over. Just last week a woman announced loudly enough for all to hear in the recovery room, that she thought abortion should be illegal. Amazingly, this was her second abortion within the last few months, having gotten pregnant again within a month of the first abortion. The nurse handled it by talking about all the carnage that went on before abortion was legalized and how fortunate she was to be receiving safe, professional care. However, this young woman continued to insist it was wrong and should be made illegal. Finally the nurse said, ‘Well, I guess we won’t be seeing you here again, not that you’re not welcome.’ Later on, another patient who had overheard this exchange thanked the nurse for her remarks.” (Clinic Administrator, Alberta)
There are other stories, not that you'll read them apparently.
