Without Catholics there would be no pro-life movement.
Catholics also founded the National Right to Life Committee,
which is the oldest and the largest national pro-life organization in the United States with affiliates in all 50 states and over 3,000 local chapters nationwide.

National Right to Life Political Action Committee (NRL PAC) is the largest and most effective pro-life political action committee in the country and has been for more than 32 years.
NRL PAC‘s charge is straightforward: to actively support electable pro-life candidates for federal office who will work to further the goals of the right to life movement, focusing on the most competitive races in the nation.
The National Right to Life PAC is held in such high esteem for one simple reason: its capacity to deliver votes to elect pro-life men and women to Congress. Since its inception in 1980, the help of NRL PAC has meant a consistent advantage for pro-life candidates over pro-abortion
Cruz Sen. Ted Cruz
In 2012, 80% of the 290 federal candidates endorsed by National Right to Life PAC won their elections. Of those 290, NRL PAC actively focused in 99 of the most competitive federal races. Despite being vastly outspent by pro-abortion groups, 57 of these 99 candidates supported by NRL PAC won.
Baloney. You can't prove that and your assertion is not a fact.
The Catholic church does not own the pro-life movement any more than it owns the Bible, despite the claims of it being so.
