I think you may be generalizing a bit. Women who have had abortions come from a variety of backgrounds, from very well off to impoverished. Also, there is no set "ethnic" group for women who have had abortions.
The same goes for those who protest abortion. There is no set ethnic or financial demographic for people who protest abortion. If you have ever seen one of those March for Life demonstrations, you will know what I am talking about.
Abortion, to me is NOT morally wrong and I don't see it as a social ill brought on by how someone was raised. Lack of access to free or low cost birth control as well as in-depth, and accurate sex education is the main reason that social abortions still exist. So, in a way, yes, it is a social ill, but not one brought on by how someone was raised. People rise above how they were raised all the time. You cannot blame your childhood on your current adult life.
For any other abortion that is NOT done for social reasons (such as failed birth control...yes it can happen and does happen, rape/incest, medical conditions that are life threatening to the woman, medical defect in the fetus, etc), there is no social wrongdoing.
