Unfortunately so many anti-abortionists come across as irrational, obsessive fanatics who are just as dangerous as the taliban in their attitude to women. They don't tend to be very convincing to women who are frightened, sick and alone.
Many anti-abortionists have been very helpful to women who really don't want to have abortions, but think it might be their only option. They are the ones who don't preach, don't condemn as evil, don't try to frighten women with all sorts of pseudo-scientific so-called facts. Instead, they offer better option, giving emotional support and often financial support in a way that demonstrates they have some sympathy with a difficult situation.
Ranting and raving aren't helpful.
