Personally, I think the right-to-life movement has been pursuing an ineffective approach for years.
What effective approach do you recommend?
1. Build your pro-life campaign around the core message that legalized abortion in the U.S. was instituted by Democrats and wealthy white Republicans to control the black population.
2. (And this is the hard part) ... Promote abortion as a great public policy to control the population of Democrats -- whoever they may be (black people, liberal white suburban women, Jewish voters, etc.). Highlight all the "blue" states in recent presidential elections, and promote abortion in these particular states as a way to reduce the political influence of Democrats on our national political scene. Build the movement around this slogan: "Aborting Democrats is an investment in the future of this country."
Watch how quickly the narrative changes when this happens.
