The people who believe that abortion is wrong feel that almost any means necessary including shock tactics - to avert the process is justified. That doesn't make their campaign, or this aspect of it, correct, it just makes it what they believe. I agree entirely with your point - no woman undertakes a termination without a deal of soul searching and pain, but I feel it is a woman's right to decide. It is a very very difficult moral and ethical question, but I don't think trying to disgust or revolt women out of their course of action is either viable, or justified, but your question concerned the stance of the alliance - and they obviously think it is justified, and it will work.
