Well, no. I’ve read, heard, and experienced for myself the fact that even pro-life believers suddenly think that THIS PARTICULAR abortion is OK, when they or their family members need it. I used to work as an escort for a women’s health clinic, which offered a variety of services, including abortion. I heard a LOT of patients who said “I don’t believe in abortion, but I need one.” Not necessarily those exact words, but that’s what they meant. We even had some pro-life repeat customers.
On the other hand, there are some pro-choice people who would never ever get an abortion themselves, they just believe that the choice should be available to those who want or need it.
