You will never be able to prevent abortions.
Uh?...we already do.
Several of my closest relatives have personally prevented many abortions
via one on one interactions and via their website:
http://www.prolife.com/My Dad personally prevented an abortion.
Close to 85-90% of Counties in the United States do not have an abortion mill.
Dozens and dozens of countries around the world ban or severely restrict abortion.
Long term science will end abortion when the horror is further exposed.
No we wont prevent every single abortion, just like we cant prevent every single arson.
But we are preventing tons of abortions which result in life.
Thankfully all of our parents Chose LIFE!
