If you want a positive way of framing abortion - let's challenge those pro-choice advocates Wendy refers to claim they want less abortions to do things that give individuals more information and local education that will reduce abortions. Or just repeatedly ask them - "what are you doing to honor your stated desire to reduce abortion".  Hit the media & grassroots youth with local activism that changes the landscape and minds of individuals. This has been the general trend of legislators since Roe anyway. For no other reason than - that's the only thing you have right now. Roe v. Wade isn't changing in the next 4 (plus) years. Even Democratically controlled legislators have (somewhat) pro-life leaders like Andy Dillon, and even the hardest core PP advocates have hard political roads if you design legislation that is common-sense (parental notification to waiting periods).

Rarely does a police interrogation elicit a confession by confronting the murder suspect as an evil killer and saying nothing else.  The good interrogator finds the underlying motive or human failing of the suspect and either earns some trust from the suspect or gets the suspect to see their actions in a new way from outside (and in those cases be genuinely remorseful).  Only when individuals wanting abortions can see the situation not from their own limited self-interest or personal justification perspective can you hope to get them to change their minds; and only when pro-life supporters have compassion for personal struggles causing the desire for an abortion will the public move en masse. Even Christ himself offers forgiveness to all, and his life's behavior was modeled this way.
