The message of pro-life is, that abortion is always bad. Pro-choice's message, however, isn't that abortion is always good...
Actually, much of the pro-abortion propaganda I have seen paints abortion as a wonderful thing, a magical solution, easier as pulling a tooth and devoid of long term consequences. That's one of the things that bother me about it.
The other thing that bothers me about pro-abortion people is their reticence to call it by its name, using the euphemism "choice" instead. For me "choice" means eating whatever ice-cream flavor you want.
On the other hand anti-abortion people are equally ridiculous on their arguments (based on religious scripture instead of medical or scientific data) and they are equally afraid to call things by their name.
