I don't think it does at all. I can't know what factors he was considering when he said that, but it's highly possible that he was criticizing the idea (promoted by abortion advocates) that a large number of abortions take place because of rape pregnancies. Dragging up rape victims as a reason all abortion for any reason should be encouraged is far more stigmatizing to rape victims, IMHO.
(8.0% in a sample of 405 women from a national random-digit dialing sample of households in USA)
Yes, I am aware of that quote in the article that I linked. The authors quoted it from another journal article as background for their study, and actually should have not used that reference, because it's very poor quality and should not have been published, IMO. The section I linked was the authors' analysis of experimental data they generated themselves, which I consider much more reliable than that one reference they mentioned.
First, it's ludicrous (because of the physical and mental trauma of rape) to think that the incidence of pregnancy from rape would be HIGHER than the 3.1% they said result from a one-time occurrence of consensual intercourse.
Second, because that referenced "study" was a random telephone survey, which makes its validity extremely questionable. A reliable study would depend on police and medical records to correlate confirmed rapes with confirmed pregnancies. Researchers performing that kind of study would probably examine hundreds of cases in order to do a proper statistical analysis.
Third, because in that sample size of 405 women, I doubt there are enough rape victims to make ANY kind of statistically significant assessment. According to a NY Times article, Nearly 1 in 5 Women in U.S. Survey Say They Have Been Sexually Assaulted (a figure which is also questionable, but I won't go into that), which would mean out of 405 women, there might be around 81 rape victims, of which 6 or 7 claim to have gotten pregnant. You simply cannot say with statistical certainty that 6 or 7 pregnancies out of 81 rape victims equates to an 8% pregnancy rate. Furthermore, once those rapes are broken down into categories for statistical analysis (e.g. morning-after pill: y/n, vaginal penetration: y/n, stranger forced rape vs. consensual statutory rape, etc.), the resulting categories would be so tiny that meaningful statistical analysis cannot be done.
Let’s say it’s four or five percent, not eight percent ... really, does it matter? Does that mean this particular five percent of women are somehow culpable? He could have said very few abortions, statistically, are due to rape. This is an indisputable fact. I don’t think anyone would have been offended by this statement of fact. Apparently, different people heard different things when he made this statement ... you and I included. This means he is a poor communicator. The pro-life movement needs someone who can articulate our values in an clear manner. I think he’s done more damage to the cause by his careless, and in my opinion, insulting statement.
